1.2 System Overview The WS2000 Wireless Switch provides a low-cost, feature-rich option for sites with one to six Access Ports. The WS2000 Wireless Switch works at the center of a network’s infrastructure to seamlessly and securely combine wireless LANs (WLANs) and wired networks. The switch sits on the network. Wireless Access Ports connect to one of the six available ports on the switch and the external wired network (WAN) connects to a single 10/100 Mbit/sec. WAN port. Mobile units (MUs) associate with the switch via an Access Port. When an MU contacts the switch, the switch cell controller services attempt to authenticate the device for access to the network. The WS2000 Wireless Switch acts as a WAN/LAN gateway and a wired/wireless switch.

1.2.1 Management of Access Ports This wireless switch provides six 10/100 Mbit/sec. LAN ports for internal wired or wireless traffic. Four of these ports provide IEEE 802.3af-compliant Power over Ethernet (PoE) support for devices that require power from the Ethernet connection (such as Access Ports). Administrators can configure the six ports to communicate with a private LAN or with an Access Port for a wireless LAN (WLAN). The switch provides up to four extended service set identifiers (ESSIDs) for each Access Port connected to the switch.

1.2.1.1 Firewall Security The LAN and Access Ports are placed behind a user-configurable firewall that provides stateful packet inspection. The wireless switch performs network address translation (NAT) on packets passing to and from the WAN port. This combination provides enhanced security by monitoring communication with the wired network.

1.2.1.2 Wireless LAN (WLAN) Security Administrators can configure security settings independently for each ESSID. Security settings and protocols available with this switch include: • Kerberos • WEP-64 • WEP-128 • 802.1x with RADIUS • 802.1x with Shared Key • KeyGuard • WPA/WPA2-TKIP • WPA2/CCMP (802.11i)

1.2.1.3 VPN Security Virtual Private Networks (VPNs) are IP-based networks that use encryption and tunneling to give users remote access to a secure LAN. In essence, the trust relationship is extended from one LAN across the public network to another LAN, without sacrificing security. A VPN behaves similarly to a private network; however, because the data travels through the public network, it needs several layers of security. The WS2000 Wireless Switch acts as a robust VPN gateway.

2-2 WS2000 Wireless Switch System Reference Guide

2.1 Getting Started with the WS2000 Wireless Switch This section provides just enough instruction to set up the WS2000 Wireless Switch, connect an Access Port, and test communications with a single mobile unit (MU) and the wide area network (WAN). The configuration suggestions made here are just the minimum needed to test the hardware. Once finished with this section, additional configuration settings are required. This section covers the following topics: • Step 1: Install the switch and connect it to the WAN, a stand alone computer, and an Access Port • Step 2: Set up administrative communication to the switch • Step 3: Set the basic switch settings

• Step 5: Configure Subnet1 • Step 6: Configure the WAN Interface • Step 7: Enable Wireless LANs (WLANs) • Step 8: Configure WLAN Security • Step 9: Test Connectivity

• Step 4: Configure the LAN interface

Step 1: Install the Switch To install the WS2000 Wireless Switch hardware, follow the directions in the WS2000 Wireless Switch Quick Installation Guide found in the box with the switch and on the CD-ROM that is distributed with the switch. These instructions describe how to: • Select a site (desk, wall, or rack) for the switch • Install the switch using the appropriate accessories for the selected location • Connect devices to WAN and LAN ports (using standard CAT-5 cables) • Interpret the port LEDs on the front of the switch After the switch is mounted and powered up, connect the following items to the switch: 1. Connect the WAN to the switch (using the WAN port) with a CAT-5 Ethernet cable. The LEDs for that port should start to flash. 2. Connect an Access Port to the switch using a CAT-5 Ethernet cable using one of the six LAN ports. If the Access Port requires PPPoE, connect the Access Port in ports 1, 2, 3, or 4. Ports 5 and 6 do not provide power. 3. Have a mobile “wireless” device available to test communication with the Access Port. NOTE: Access Ports must be connected to the LAN ports of the wireless switch to enable configuration of the Access Port related settings.

Step 2: Set Up Administrative Communication to the Switch Before the configuration process can begin, establish a link with the wireless switch. 1. Connect a “wired” computer to the switch (in any one of the available LAN ports) using a standard CAT-5 cable. 2. Set up the computer for TCP/IP DHCP network addressing and make sure that the DNS settings are not hard coded. 3. Start up Internet Explorer (with Sun Microsystems’ Java Runtime Environment (JRE) 1.4 or higher installed) and type the following IP address in the address field: 192.168.0.1

Getting Started 2-3

NOTE: For optimum compatibility use Sun Microsystems’ JRE 1.4 or higher (available from Sun’s website), and be sure to disable Microsoft’s Java Virtual Machine if it is installed.

The following screen displays.

4. Log in using admin as the User ID and symbol as the Password. 5. If the login is successful, the following dialog window displays.

Enter a new admin password in both fields, and click the Update Password Now button. When the admin password has been updated, the following message displays, and you are prompted to change the country of operation for the switch.

6. Select and change the country from the Country drop-down list of the System Settings screen. 7. Click the Apply button to save the changes. The System Setting screen is displayed.

2-4 WS2000 Wireless Switch System Reference Guide

Step 3: Set the Basic Switch Setting 1. Enter a System Name for the wireless switch. The specified name appears in the lower-left corner of the configuration screens, beneath the navigation tree. This name can be a useful reminder if multiple Motorola wireless switches are being administered. 2. Enter a text description of the location of the switch in the System Location field. This text is used as a reminder to the network administrator and is also used to set the location variable if the switch is administered using SNMP. 3. In the Domain Name field, enter the name of the domain this switch is a member of. This value is returned along with the system name for a Reverse DNS Query on the switch. 4. Enter an email address for the administrator in the Admin Email Address field. The switch uses this address for sending SNMP-related and other administration-related messages to the administrator. 5. Enter the IP address of the DNS Name Server in the DNS Server IP Address field. The switch uses this field to resolve FQDN information provided in the NTP configuration page. See Specifying a Network Time Protocol (NTP) Server for more information. 6. Select the Country for the switch from the drop-down menu. Selecting the correct country is extremely important. Each country has its own regulatory restrictions concerning electromagnetic emissions and the maximum RF signal strength that can be transmitted by Access Ports. To ensure compliance with national and local laws, be sure to set this field accurately. 7. Keep the Enable DNS Relay option checked. If not checked, clients on the LAN side of the WS2000 will not be able to use a DNS server to resolve URLs. 8. Click Apply to save changes. Unapplied changes are lost if the administrator navigates to a different screen.

Getting Started 2-5

NOTE: The WS2000 switch is shipped with an open default SNMP configuration: Community: public, OID: 1.3.6.1, Access: Read-only Community: private, OID: 1.3.6.1, Access: Read-write If your switch has these settings, it is important to change them immediately; otherwise, users on the same network will have read-write access to the switch through the SNMP interface. Select [System Configuration] --> SNMP Access from the left menu to examine the settings and change them, if necessary.

Step 4: Configure the LAN Interface The first step of network configuration process is to figure out the topology of the LAN. The WS2000 Wireless Switch allows the administrator to enable and configure six different subnets. The administrator can assign an IP address, port associations, and DHCP settings for each subnet.

Enable Subnet1 Select LAN under the Network Configuration group from the left menu. Use the LAN configuration screen to view a summary of physical-port addresses and wireless LANs (WLANs) associated with the six supported subnets, and to enable or disable each configured subnet.

1. In the LAN screen, the administrator can enable up to six subnets. Make sure that the check box to the left of Subnet1 line is enabled. Each enabled subnet shows up in the directory tree in the left column of the configuration screens. Consider disabling a previously configured subnet if its assigned ports are no longer in use, or to consolidate the LANâ&#x20AC;&#x2122;s communications on fewer subnets. The rest of the information on this screen is summary information; it is collected from other screens (such as the subnet configuration screens) where the administrator can set the data. Network

Network (subnet) name is a descriptive string that should describe the subnetâ&#x20AC;&#x2122;s function. The WS2000 Network Management System uses subnet names throughout the configurations screens.

2-6 WS2000 Wireless Switch System Reference Guide

Address

This IP address allows users from outside the subnet (whether from the WAN or from another subnet from the same switch) to access the right subnet. An IP address uses a series of four numbers that are expressed in dot notation, for example, 194.182.1.1.

Interfaces

The Interfaces field displays which of the six physical LAN ports are associated with the subnet. The possible ports are: P1 (port 1), P2, P3, P4, P5, and P6 (from left to right facing the front of the switch). The administrator assigns a port to a subnet to enable access to the device(s) connected to that port. The administrator can assign a port to only one subnet. The Interfaces field also lists the WLANs that are associated with the subnet.

Step 5: Configure Subnet1 The WS2000 Network Management System allows the administrator to define and refine the configuration of the enabled subnets. Each of six subnets (short for “subnetworks”) can be configured as an identifiably separate part of the switch-managed local area network (LAN). Each subnet can include some combination of assigned ports and associated wireless LANs (WLANs). 1. Select [Network Configuration] --> LAN --> Subnet1 from the list on the left. The following screen appears for the selected subnet.

2. Check to make sure that all the ports and WLAN1 are selected for this subnet. WLAN1 should automatically be included if the switch and the Access Port are communicating properly. If WLAN1 is not present in the list, check the following: • The power to the Access Port • The connections between the switch and the Access Port • The LEDs to make sure that lights are on and flashing

Getting Started 2-7

3. For this initial configuration, ensure that This interface is a DHCP Server is enabled. If so, the switch sets the IP addresses automatically for the mobile devices. This value can be changed at any time in the future. All other default settings are fine for the system test. DHCP is a protocol that includes mechanisms for IP address allocation and delivery of host-specific configuration parameters from a DHCP server to a host. Some of these parameters are IP address, network mask, and gateway. The switch includes internal DHCP server and client features, and the subnet’s interface can use either capability. 4. Click the Apply button to save changes.

Step 6: Configure the WAN Interface A wide area network (WAN) is a widely dispersed telecommunications network. In a corporate environment, the WAN port might connect to a larger corporate network. For a small business, the WAN port might connect to a DSL or a cable modem to access the Internet. The WS2000 Wireless Switch includes one WAN port. In order to set up communications with the outside world, select [Network Configuration] --> WAN from the left menu. The following WAN configuration page appears.

Communicating with the Outside World 1. Click the Enable WAN Interface check box to enable a connection between the switch and a larger network or the outside world through the WAN port. 2. If this switch should be a DHCP client (A DHCP client get it’s IP address automatically from a DHCP server or a switch), check the This interface is a DHCP Client check box to enable it. If This interface is DHCP Client is checked, the switch is limited to one WAN IP address. This choice is required when: • The host router or switch on the WAN communicates with the WS2000 Wireless Switch using DHCP. • The switch interfaces with an Internet Service Provider (ISP) that uses DHCP addressing.

2-8 WS2000 Wireless Switch System Reference Guide

NOTE: This setting is independent from the DHCP settings for the switch’s internal subnets.

3. If This interface is DHCP Client is not checked, other fields in the screen are enabled. To find out the information to enter into these fields, contact your network administrator or the ISP that provided the cable modem or DSL router. All fields take standard IP addresses in the form xxx.xxx.xxx.xxx. • IP Address refers to the IP address that the outside world uses to address this WS2000 Wireless Switch. • Click the More IP Addresses button to specify additional static IP addresses for the switch. Additional IP addresses are required when users within the LAN need dedicated IP addresses, or when servers in the LAN need to be accessed (addressed) by the outside world. The pop-up window allows the administrator to enter up to eight WAN IP addresses for the switch. • The Subnet Mask is the mask used for the WAN. • The Default Gateway is the address of the device that provides the connection to the WAN (often a cable modem or DSL router). • The two DNS Server fields specify DNS addresses of servers that can translate domain names, such as www.motorola.com, into IP addresses that the network uses when passing information. The Secondary DNS Server acts as a backup to the Primary DNS Server when the primary server is not available.

Setting Up Point-to-Point over Ethernet (PPPoE) Communication Point-to-Point over Ethernet (PPPoE) provides the ability to connect a network of hosts through a simple device to a remote access concentrator. Many DSL providers require that their clients communicate using this protocol. The facility allows the ISP to control access, billing, and type of service provided to clients on a per-user or per-site basis. Check with the network administrator or ISP to determine whether to enable this feature, and, if so, find out the username and password required for authentication. To set up PPPoE, click on the PPPoE tab under the WAN screen. 1. Check Enable in the PPP over Ethernet area to enable the PPPoE protocol for high-speed connections. 2. Enter the Username and Password required for authentication. The username and password are for the switch’s router to use when connecting to the ISP. When the Internet session starts, the ISP authenticates the username. 3. Set the Idle Time in seconds to an appropriate number. This number is the amount of time the PPPoE connection will remain idle before it disconnects. 10000 seconds default idle time is appropriate for most situations. 4. Check Keep Alive to instruct the switch to continue occasional communications over the WAN even when client communications to the WAN are idle. Some ISPs terminate inactive connections, while others do not. In either case, enabling Keep-Alive mode keeps the switch’s WAN connection alive, even when there is no traffic. If the ISP drops the connection after reaching the maximum idle time, the switch automatically reestablishes the connection to the ISP. 5. Select the appropriate WAN authentication method from the drop-down menu. Collect this information from the network administrator. Select between None, PAP, CHAP, or PAP or CHAP.

Getting Started 2-9

CHAP

A type of authentication in which the user logging in uses a secret information and some special mathematical operations to calculate a numerical value. The server, the user is logging into, knows the same secret value and performs the same mathematical operations to arrive at a value. If the values match, the user is authorized to access the server. One of the numbers used in the mathematical operation is changed after every log-in. This is to protect the server against an intruder secretly copying a valid authentication session and replaying it later to log in.

PAP

An identity verification method used to send a username and password over a network to a computer that compares the username and password to a table listing authorized users. This method of authentication is less secure, because the username and password travel as clear text that a hacker could read and use to launch an attack.

Step 7: Enable Wireless LANs (WLANs) The WS2000 Wireless Switch works either in a wired or wireless environment; however, the power of the switch is associated with its support of wireless networks. In order to use the wireless features of the switch, the administrator needs to enable up to four wireless LANs (WLANs). To start the WLAN configuration process, select the [Network Configuration] --> Wireless item from the left menu. The following Wireless screen appears.

Wireless Summary Area The top portion of the window displays a summary of the WLANs that are currently defined. This is the screen in which the administrator can enable or disable a WLAN. At first, eight WLANs are listed WLAN1, WLAN2, WLAN3, WLAN4, WLAN5, WLAN6, WLAN7 and WLAN8; however, only WLAN1 is enabled. 1. Verify that WLAN1 is enabled (checked) and associated with Subnet1.

2-10 WS2000 Wireless Switch System Reference Guide

2. Verify that Access Port 1 is shown in the Access Ports Adopted field to the right. If it is not, verify the connection between the switch and the Access Port. The current settings for the associated Subnet and adopted Access Ports are displayed on this screen; however, the screen associated with each WLAN (under [Network Configuration] --> Wireless) is where the settings and rules for adopting Access Ports can be modified. Use the AP Adoption Configuration tab to assign Access Ports to a particular WLAN. The switch can adopt up to six Access Ports at a time, but the list of allowed Access Port addresses (displayed in this area) can exceed six in number. A dual-radio 802.11a/b Access Port counts as one Access Port with respect to the maximum allowed; however, each radio is listed as a separate Access Port. This adoption list identifies each Access Port by its Media Access Control (MAC) address. This address is the Access Portâ&#x20AC;&#x2122;s hard-coded hardware number that is printed on the bottom of the device. An example of a MAC address is 00:09:5B:45:9B:07. The default setting associates all adopted Access Ports with WLAN1.

Step 8: Configure WLAN Security In the previous step, the administrator set parameters for each WLAN that fine tune the performance of the WLAN. In addition, the administrator can set the type and level of security for each WLAN. These security measures do not control communications from the WAN; instead, they control communication from the clients within the WLAN. In the [Network Configuration] --> Wireless --> <WLAN name> --> <WLAN Name> Security screen, the administrator can set the user authentication method and the encryption method, as well as define a set of rules that control which MUs can communicate through the WLAN.

Getting Started 2-11

Setting the Authentication Method The authentication method sets a challenge-response procedure for validating user credentials such as username, password, and sometimes secret-key information. The WS2000 Wireless Switch provides two methods for authenticating users: 802.1x EAP and Kerberos. The administrator can select between these two methods. For testing connectivity, WLAN security is not an issue, so there is not reason to enable authenticationâ&#x20AC;&#x201D;the default setting (No Authentication) is sufficient.

Setting the Encryption Method Encryption applies a specific algorithm to data to alter its appearance and prevent unauthorized reading. Decryption applies the algorithm in reverse to restore the data to its original form. Sender and receiver employ the same encryption/decryption method. Wired Equivalent Privacy (WEP) is a security protocol specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b. WEP is designed to provide a WLAN with a level of security and privacy comparable to that of a wired LAN. WEP might be all that a small-business user needs for the simple encryption of wireless data. However, networks that require more security are at risk from a WEP flaw. An unauthorized person with a sniffing tool can monitor a network for less than a day and decode its encrypted messages. For the connectivity test, set WEP 128 encryption. This ensures that communications with the switch are secure enough for this stage. Later on, increasing the security level might be necessary. 1. Select the WEP 128 (104-bit key) option. 2. To use WEP encryption with the No Authentication selection, click the WEP Key Settings button to display a sub-screen for entering keys.

3. Add a key to Key #1, and use that key with the mobile unit. The keys consist of 26 hexadecimal (0-9, A-E) characters. When finished, click the Ok button to close this screen an return to the WLAN Security screen. 4. Click the Apply button in the WLAN Security screen to save changes.

Mobile Unit Access Control List (ACL) This list is used to specify which mobile units can or cannot gain access to the WLAN. The list employs an adoption rule for allowing or denying specific mobile units by way of exception. By default, all mobile units can gain access.

2-12 WS2000 Wireless Switch System Reference Guide

Step 9: Test Connectivity At this point, the switch is set up to allow mobile units to access the LAN. 1. Check and ensure that the MU is setup as a DHCP client. 2. Set the MU to use WEP 128 bit encryption. Use the same key as was entered in the WEP Key Setting dialog. You might need to restart the MU after changing the settings. 3. Open a Web browser and type the IP address: 192.168.0.1. The WS2000 Switch Management screen should appear. If it does not, go back to the wired system used to configure the switch and see if the mobile device appears in the MU Stats screen ([Status & Statistics] --> MU Stats). If it does not appear on the MU Stats screen, recheck the network and WEP settings on the mobile device. 4. In the Web browser, enter a URL for a site (such as www.motorola.com) on the WAN. If the site does not appear, go to the WAN Stats screen ([Status & Statistics] --> WAN Stats) to review the status of the WAN connection.

2.2 Where to Go from Here? When full connectivity has been verified, the switch can be configured further to meet the needs of the organization. Refer to the two case studies provided with this reference for specific installation examples. These case studies describe the environment, the desired features, and the configuration selections that were made in two different usage scenarios. â&#x20AC;˘ Case 1: Retail Use Case (with handheld terminals, wireless printers, wired POS, secured access to in-store server, and public access to WAN) â&#x20AC;˘ Case 2: Field Office Use Case (with 3 WAN IP addresses, VPN passthrough, RADIUS server, and full-access between subnets)

3-2 WS2000 Wireless Switch System Reference Guide

3.1 Enabling Subnets for the LAN Interface Subnets are used to maximize the available network addresses and to logically separate the existing organizational network into smaller related networks. The WS 2000 Wireless Switch allows administrators to enable and configure six different subnets for each switch. Administrators can assign IP addresses, port associations, DHCP settings, and security settings for each subnet. This System Reference Guide provides two case studies that demonstrate how requirements for network access and capabilities drive the decisions of how to configure the subnets.

3.1.1 Defining Subnets Select LAN under the [Network Configuration] group from the left menu. Use the LAN configuration screen to view a summary of physical-port addresses and Wireless LANs (WLANs) associated with the six supported subnets, and to enable or disable each configured subnet.

1. Check the box to the left of a subnet to enable it. Up to six subnets can be enabled to use the wired and/ or wireless connections of the switch-managed LAN. Enable multiple subnets to divide the communications of different business areas or operations. Each enabled subnet shows up in the directory tree in the left column of the configuration screens. Consider disabling a previously configured subnet if its assigned ports are no longer in use, or to consolidate the LANâ&#x20AC;&#x2122;s communications on fewer subnets. 2. Click Update DNS for all Subnets to asynchronously invoke the Dynamic DNS update module. This module checks the expired and valid DHCP leases for each of the subnets and adds or deletes entries to the Dynamic DNS table accordingly. 3. Click Enable STP to enable STP. Spanning Tree Protocol (STP) is a protocol that ensures loop-free topology for any bridged LAN. This feature is not enabled by default. NOTE: STP is applied for mesh networks even if it is not enabled through the LAN screen.

LAN/Subnet Configuration 3-3

4. Click Apply to save changes. All “unapplied” changes are lost when the administrator moves to a new screen. The rest of the information on this screen is summary information. It is collected from other screens (such as the subnet configuration screens) where the administrator can set the data. Network

Network (subnet) name is a descriptive string that should describe the subnet’s function. The WS2000 Network Management System uses subnet names throughout the configurations screens.

Address

Interfaces

To change features of a subnet, select [Network Configuration] --> LAN --> <subnet name> from the menu on the left.

3.2 Configuring Subnets The WS2000 Network Management System allows the administrator to define and refine the configuration of the enabled subnets. Each of the six subnets (short for “subnetworks”) can be configured as an identifiably separate part of the switch-managed Local Area Network (LAN). Each subnet can include some combination of assigned ports and associated Wireless LANs (WLANs). To configure an enabled subnet, select the subnet name from the [Network Configuration] --> LAN list in the left. The following screen appears for the selected subnet.

3-4 WS2000 Wireless Switch System Reference Guide

1. Change the Name of the subnet to use a descriptive name that indicates something about the subnet. The name can contain seven characters, including spaces and numbers. It will appear in the left menu under the LAN menu item. 2. Set an IP address to be used for the subnet. The switch uses the IP address to refer to a particular subnet. This IP address could be a WAN address; but is generally a non-routable address. An IP address uses a series of four numbers that are expressed in dot notation, for example, 194.182.1.1. 3. Set the Network Mask for the IP address. A network mask uses a series of four numbers that are expressed in dot notation, similar to an IP number. For example, 255.255.255.0 is a network mask. 4. Select a port or WLAN from the list of Interfaces to associate it with the subnet. Six LAN ports are available on the switch. Assign from one to six ports to a subnet. Two subnets cannot use the same port. However, multiple ports can be assigned to one subnet. Eight WLANs are available. WLAN assignments are logical designations. Associate from zero to three WLANs with a subnet. Two subnets cannot use the same WLAN. However, multiple WLANs can be associated with one subnet. If two or three WLANs are associated with one subnet, each port dedicated to that subnet can use any of the associated WLANs. 5. Click the Add button to add it to the Interfaces list. To remove an interface, select that interface from the Assigned list and click the Delete button. NOTE: Note that wireless devices cannot access the switch unless a WLAN is configured and associated with a subnet. (This process is described in detail in Configuring Wireless LANs section of this document.)

LAN/Subnet Configuration 3-5

3.2.1 The DHCP Configuration DHCP is a protocol that includes mechanisms for IP address allocation and delivery of host-specific configuration parameters from a DHCP server to a host. Some of these parameters are IP address, network mask, and gateway. The switch includes internal DHCP server and client features, and the subnet’s interface can use either capability. 1. Click the appropriate radio button to select one DHCP setting for the subnet’s interfaces: • Select This interface does not use DHCP to disable DHCP on this subnet and specify IP addresses manually. • Select This interface is a DHCP Client if this subnet obtains IP parameters from a DHCP server outside the switch. • Select This interface is a DHCP Server to enable the switch’s DHCP server features. • Select This interface is a DHCP Relay to use an external DHCP server to provide DHCP information to clients on this subnet. Use the associated field to enter the IP address for the external DHCP Server. 2. If This interface is a DHCP Server is the selected option, fill in the Address Assignment Range fields. These fields allow the administrator to assign a range of IP addresses to devices as they connect. 3. Set the Advanced Settings, if necessary. 4. Click the Apply button to save all changes.

3.2.2 Advanced DHCP Settings 1. Click the Advanced DHCP Server button to display a sub-screen to further customize IP address allocation.

3-6 WS2000 Wireless Switch System Reference Guide

2. If Dynamic DNS services are needed on the subnet, check the box labeled Enable Dynamic DNS. Enabling Dynamic DNS will allow domain name information to be updated when the IP address associated with that domain changes. When a MU associates and gets an IP address from the DHCP server, the DHCP server then updates the DNS server with the IP allotted to the corresponding hostname when DDNS is enabled. Any DHCP client can send the User Class Id either in the Single or Multiple user class ID format. The Single or Multiple User class option is provided to enable the switch to interpret the correct format in which the user class ID is sent by the client. The switch then retrieves the correct value of the user class ID sent by the DHCP client based on the selected format. This same user class ID format is used for the DDNS messages. 3. Specify the address of a Primary DNS Server. The Internet Server Provider (ISP) or a network administrator can provide this address. A DNS server translates a domain name, such as www.symbol.com, into an IP address that networks can use. 4. Specify the address of a Secondary DNS Server if available. 5. Specify the Default Gateway IP address for this subnet's presence on the network. This IP address should be the same as used on the Subnet screen. 6. If your network has a Windows Internet Name Service (WINS) server, specify its IP address in the WINS Server field. A WINS server allows you to map NetBIOS names to IP addresses. 7. Specify a DHCP Lease Time period in seconds for available IP addresses. The DHCP server grants an IP address for as long as it remains in active use. The lease time is the number of seconds that an IP address is reserved for re-connection after its last use. Using very short leases, DHCP can dynamically reconfigure networks in which there are more computers than there are available IP addresses. This is useful, for example, in education and customer environments where mobile-unit users change frequently. Use longer leases if there are fewer users. 8. If the MUs on this subnet are members of a domain, enter that name in the Domain Name field and it will be sent out via DHCP to all MUs associated with this subnet. 9. DNS Forward Zone is used for maintaining DomainName to Address mappings used by the DNS server. 10.Use the TFTP Server Address to provide the IP address of the TFTP Sever. The TFTP server address is the address of the boot server. 11.Use the Bootfile text box to provide the path to the Boot file. 12.Option 189 is used to specify the IP address and port address of a Wireless Internet Access Provide (WIAP) enabled switch, a switch that can adopt Access Ports in WIAP mode. This field accepts a comma separated list, for example, 192.168.0.1:200, 100.1.200.24:24576. Only port 24576 is supported. 13.Option 43 is used to specify the IP address of a WIAP enabled switch, a switch that can adopt Access Ports in WIAP mode. This field accepts a comma separated list, for example, 192.168.0.1, 100.1.200.24

LAN/Subnet Configuration 3-7

14.Use the Static Mappings table to associate static (or fixed) IP addresses with MAC addresses of specific wireless devices. Every wireless, 802.11x-standard device has a unique Media Access Control (MAC) address. This address is the deviceâ&#x20AC;&#x2122;s hard-coded hardware number (shown on the bottom or back). An example of a MAC address is 00:09:5B:45:9B:07.This MAC table of specified devices provides corresponding static IP addresses for users, mobile units, and applications that may prefer or require such access.

3.3 Configuring Subnet Access The WS2000 Network Management System allows the administrator to set up access rules for subnet-tosubnet and subnet-to-WAN communication. These access rules control communication between subnets and the outside world (the WAN). Select [Network Configuration] --> Firewall --> Subnet Access to get to the Subnet Access screen.

3.3.1 The Access Overview Table In the overview table, each of the rectangles represents a subnet association. The three possible colors indicate the current access level, as defined, for each subnet association. Color

Access Type

Description

Green

Full Access

No protocol exceptions (rules) are specified. All traffic may pass between these two areas.

Yellow

Limited Access

One or more protocol rules are specified. Specific protocols are either enabled or disabled between these two areas. Click the table cell of interest and look at the exceptions area in the lower half of the screen to determine the protocols that are either allowed or denied.

Red

No Access

All protocols are denied, without exception. No traffic will pass between these two areas.

3-8 WS2000 Wireless Switch System Reference Guide

3.3.2 The Access Exception Area In the lower half of the screen, the access is controlled by specific rules that control the protocols that are allowed or denied between the two subnets or the subnet and the WAN. All rules are added to the exception table. The Allow or Deny menu item applies to all entries in the table. There are two ways to add entries (access rules) to the table. The first is by checking the check boxes for specific protocols (on the left). The second is by adding rules for specific port numbers by clicking the Add button and filling in the necessary information. A combination of the two methods can be used to add multiple entries to the table. You can allow or deny communication through specific protocols using the following process: 1. Click in a cell of the table that represents the subnet-to-subnet (or subnet-to-WAN) relationship to define. All access rules (if any are defined) appear in the table in the lower-half of the screen. 2. Use the pull-down menu above the list to Allow or Deny all the entries specified in the exception table. You cannot allow some protocols (or ports) and deny others. 3. Enable or disable logging of firewall access by using the Enable logging check box. When enabled, a log entry is created every time a packet is denied by the action “Deny”. A log entry is created once per session for packets that match the firewall rules when the action is “Allow”. 4. From the list of check boxes on the left side, select those protocols to allow or deny. The protocols are automatically added to the table with the relevant Name, Transport, Start Port, and End Port information. The available protocols are described in the table below. Protocol

Transport, Port Used

Description

HTTP

TCP, 80

Hypertext Transfer Protocol (HTTP) is the protocol for transferring files on the World Wide Web. HTTP is an application protocol that runs on top of the TCP/IP suite of protocols, the foundation protocols for the Internet.

TELNET

TCP, 23

TELNET is the terminal emulation protocol of TCP/IP. TELNET uses TCP to achieve a virtual connection between server and client, then negotiates options on both sides of the connection.

FTP

TCP, 21

File Transfer Protocol (FTP) is an application protocol that uses the Internet’s TCP/IP protocols. FTP provides a simple and efficient way to exchange files between computers on the Internet.

SMTP

TCP, 25

Simple Mail Transfer Protocol (SMTP) is a TCP/IP protocol used for sending and receiving email. Due to its limited ability to queue messages at the receiving end, SMTP is often used with POP3 or IMAP. SMTP sends the email, and then POP3 or IMAP receives the email.

POP

TCP, 109:110

Post Office Protocol (POP3) is a TCP/IP protocol intended to permit a workstation to dynamically access a maildrop on a server host. A workstation uses POP3 to retrieve email that the server is holding for it.

DNS

TCP+UDP, 53

Domain Name Service (DNS) protocol searches for resources using a database that is distributed among different name servers.

You can make changes to the information automatically filled into the table; however, note that changes in the selected transport type can change the port numbers that can be specified in the table. 5. To add an access rule for a protocol, port, or transport other than the ones available from the check boxes on the left, click the Add button. An empty row is added to the table.

LAN/Subnet Configuration 3-9

• Specify a Name to identify the new access rule. For example, this could be the name of a particular application. • Select a transport type from the Transport column’s pull-down menu. The available transports are: Transport

Description

ALL

This selection designates all of the protocols displayed in the table’s pull-down menu, as described below.

TCP

Transmission Control Protocol (TCP) is a set of rules used with Internet Protocol (IP) to send data as message units over the Internet. While IP handles the actual delivery of data, TCP keeps track of individual units of data called packets. Messages are divided into packets for efficient routing through the Internet.

UDP

User Datagram Protocol (UDP) is mostly used for broadcasting data over the Internet. Like TCP, UDP runs on top of Internet Protocol (IP) networks. Unlike TCP/IP, UDP/IP provides very few error recovery services and methods. UDP offers a way to directly connect, and then send and receive datagrams over an IP network.

ICMP

Internet Control Message Protocol (ICMP) is tightly integrated with IP. ICMP messages, delivered in IP packets, are used for out-of-band messages related to network operation. Because ICMP uses IP, ICMP packet delivery is unreliable. Hosts cannot count on receiving ICMP packets for a network problem.

Authentication Header (AH) is one of the two key components of IP Security Protocol (IPSec). The other key component is Encapsulating Security Protocol (ESP), described below. AH provides authentication, proving the packet sender really is the sender, and the data really is the data sent. AH can be used in transport mode, providing security between two end points. Also, AH can be used in tunnel mode, providing security like that of a Virtual Private Network (VPN).

ESP

Encapsulating Security Protocol (ESP) is one of the two key components of IP Security Protocol (IPSec). The other key component is Authentication Header (AH), described above. ESP encrypts the payload of packets, and also provides authentication services. ESP can be used in transport mode, providing security between two end points. Also, ESP can be used in tunnel mode, providing security like that of a Virtual Private Network (VPN).

GRE

General Routing Encapsulation (GRE) supports VPNs across the Internet. GRE is a mechanism for encapsulating network layer protocols over any other network layer protocol. Such encapsulation allows routing of IP packets between private IP networks across an Internet that uses globally assigned IP addresses.

• Specify port information for the protocol. If the protocol uses only one port, enter the same port number in the Start Port and End Port columns, or leave the End Port column blank. Otherwise, use both columns for an entry that has a range of ports. 6. To enable or disable logging for a particular firewall rule, select the appropriate option from the pulldown menu for the field. When default option is selected, logging will depend on the global Enable logging field. To enable logging, select enable. 7. Click the Apply button to save changes.

3.4 Advanced Subnet Access Settings There can be situations in which the standard subnet access setting process is not specific enough for the needs of an organization. Instead, access or firewall rules need to be defined based upon destination and source IP addresses, transport types, and ports. The Advanced Subnet Access screen allows the administrator to create more complicated inbound and outbound policies. Select [Network Configuration] --> Firewall --> Advanced Subnet Access from the left menu. The screen consists of two areas. The Settings area enables or disables the data found on this screen. The Firewall Rules area displays the currently defined and active firewall rules. This area will display either the inbound or outbound rules. The rules are applied in the order that they are listed. The rules at the top of the list take precedence over the rules lower in the list.

1. To enable the advanced access settings, check the Override Subnet Access and NAT settings box. The rest of the screen will become active. When this box is not checked, the settings in both the Subnet Access screen (under Firewall) and the NAT screen (under WAN) are disabled; the switch will use the settings found on this screen instead. 2. If you want the application to translate the subnet access settings into Firewall Rules (displayed in the lower area), click the Import rules from Subnet Access button. This button removes the need for the administrator to reenter the information defined on the Subnet Access screen.â&#x20AC;&#x2DC; Next, add, delete, or modify rules in the Firewall Rules list, as required. 3. Select Inbound or Outbound from the pull-down menu at the top of the Firewall Rules area, to display either the inbound (data entering the LAN) or outbound (data exiting the LAN) rules. 4. To modify a rule, select the rule from the Firewall Rules list, then edit the fields by clicking in the field to modify. Often a dialog box will appear to facilitate the entry of the field data. 5. To add a rule, click the Add button and then add data to the six rule fields. Note that not all fields are required. 6. To delete a rule, select a rule from the list and click the Del button.

LAN/Subnet Configuration 3-11

7. Move rules to a higher or lower precedence by clicking the Move Up or Move Down buttons, as necessary. 8. When you have finished defining the Firewall Rules, click the Apply button to save changes. Use the following information to help set the Firewall Rule fields: • Index—The index number determines the order in which firewall rules will be executed. The rules are executed in order from lowest index number to highest number. Use the Move Up and Move Down buttons to change the index number. • Source IP—The Source IP range determines the origin address(es) for the firewall rule. To set the Source IP range, click the field and a new window will pop up to enter the IP address and a second number that indicates that number of IP numbers starting at the first address (the range). An IP address of 0.0.0.0 indicates all IP addresses. • Destination IP—The Destination IP range determines the target address(es) for the firewall rule. To configure the Destination IP range, click the field and a new window will pop up to enter the IP address and range. An IP address of 0.0.0.0 indicates all IP addresses. • Transport—To determine the transport protocol to be filtered in the firewall rule, click the field to choose from the list of protocols: Transport

• Src. Ports (Source Ports)—The source port range determines which ports the firewall rule applies to on the source IP address. To configure the source port range, click the field and a new window will pop up to enter the starting and ending ports in the range. For rules where only a single port is necessary, enter the same port in the start and end port fields. • Dst. Ports (Destination Ports)—The destination port range determines which ports the firewall rule applies to on the destination IP address. To configure the destination port range, click the field and a new window will pop up to enter the starting and ending ports in the range. For rules where only a single port is necessary, enter the same port in the start and end port fields. • Rev. NAT (Reverse NAT) (inbound) / NAT (outbound)—To enable NAT or reverse NAT for a firewall rule, enter this value. For Inbound, click the Rev. NAT field and a new window will pop up to enter the IP address and translation port for the reverse NAT host. For the Outbound direction, select the WAN (WAN1, WAN2, and so on) from the NAT field menu that is associated with the appropriate NAT definition. (See Configuring Network Address Translation (NAT)). • Action—Choose Allow or Deny from the pull-down menu in this field to determine whether the firewall rule is to allow or deny the specified rule. • Log - Choose disable or enable from the pull-down menu in this field. When enabled, the following is the behavior. • A log entry is created every time a packet that matches this rule is denied by the action “Deny”. • A log entry is created once per session for packets that match this rule is allowed access by the action “Allow”.

3.5 ALG - Configuration In certain deployment scenarios, users might need to configure how the Application Layer Gateway (ALG) checks and controls traffic destined to some specific IP address or addresses. This is specifically required in scenarios where Motorola’s Airdefence WIPS Server and Motorola’s AP300s converted to sensors are deployed. Communication between Motorola’s Airdefence Server and sensor AP300s uses proprietary protocol and uses specific ports. ALGs expects specific protocol packets on these specific ports and thus drops these communication packets as it does not confirm to the expected protocol. The ALG - Configuration screen enables users to bypass ALG checks for traffic to and from specific IP addresses. Only HTTP ALG checks can be enabled or disabled. By default, no such exceptions are defined. All traffic must pass through the firewall and ALG checks. There can be 20 such exceptions to the ALG rules. To define these ALG exception rules, select [Network Configuration] --> Firewall -> ALG Configuration. The ALG - Configuration screen displays.

LAN/Subnet Configuration 3-13

To configure ALG exception rules: 1. Click the Add button. This creates a new row in the Firewall Rules table. For the new row, the source IP (Src IP) and destination IP (Dst IP) are set to zero. Double click on them to change the IP addresses. 2. Select the destination interface Dst-Interface to which the traffic would be directed to. Select from either LAN or WAN. 3. When WAN is selected as the Dst-Interface, select the WAN interface IP address to map the source IP (Src IP). By default, the Src IP is mapped to WAN1 in the NAT column. If â&#x20AC;&#x2DC;noneâ&#x20AC;&#x2122; is selected, then the source IP is not modified and the packet is sent out as such. This field has no impact when LAN is selected as the Dst-Interface. 4. Select the appropriate action to be performed by HTTP-ALG. Select Enable to allow HTTP-AGL to process traffic. Select Disable to prevent. 5. Select the appropriate action to be performed by IPS (Intrusion Prevention System). To allow IPS to check the traffic, select Enable. To bypass this check, select Bypass. 6. Select the appropriate log settings in the Log column. To prevent logging, select Disable. Select Enable to start logging. NOTE: Twenty (20) entries can be made in the Firewall Rules table.

Select a row and click the Del button to delete it.

3.6 Bridge Configuration Bridges are data link layer devices. They operate at the Layer 2 of the OSI reference model. Bridges are generally used to connect different segments of the same network.

3-14 WS2000 Wireless Switch System Reference Guide

To configure Bridging, select [Network Configuration] --> LAN --> <subnet> and select the Bridging tab. The Bridge Config (Bridge Configuration) screen appears.

To configure the bridge: 1. Set the Priority for the bridge. Set the Priority as low as possible to force other devices within the mesh network to defer to this bridge as the root. A root bridge defines the mesh configuration. Motorola recommends assigning a Base Bridge AP with the lowest bridge priority so it becomes the root in the STP. If a root already exists, set the Bridge Priorities of new APs accordingly so that the root of the STP does not get altered. Each access point starts with a default bridge priority of 32768. 2. Set the Maximum Message age timer is used with the Message Age timer. The Message Age timer is used to measure the age of the received protocol information recorded for a port, and to ensure the information is discarded when it exceeds the value set for the Maximum Message age timer. 3. Set the Hello Timer. The Hello Time is the time between each bridge protocol data unit sent. This time is equal to 2 seconds by default, but you can tune the time to be between 1 and 10 seconds. If you drop the hello time from 2 seconds to 1 second, you double the number of bridge protocol data units sent or received by each bridge. The 802.1d specification recommends the Hello Time be set to a value less than half of the Max Message age value. 4. Set the Forward Delay. It is the time spent in the listening and learning state. This time is equal to 15 seconds by default, but you can tune the time to be between 4 and 30 seconds. The 802.1d specification recommends the Forward Delay be set to a value greater than half the Max Message age timeout value. 5. The Forwarding Table Ageout value defines the length of time an entry will remain in the a bridge's forwarding table before being deleted due to lack of activity. If the entry replenishments a destination generating continuous traffic, this timeout value will never be invoked. However, if the destination becomes idle, the timeout value represents the length of time that must be exceeded before an entry is deleted from the forwarding table. 6. To enable wireless trunking, check the Enable Wireless Trunking check box. Also provide the IDs of the VLAN which allow tunneling.

LAN/Subnet Configuration 3-15

3.7 Virtual LAN (VLAN) Configuration A Virtual Local Area Network or VLAN is a switched network that has been segmented by function or application rather than by the traditional LAN segmentation which is based on physical location. VLANs allow a greater level of flexibility than a standard LAN, and enable changes to be made to the network infrastructure without physically disconnecting network equipment. The WS 2000 Wireless Switch supports assigning one VLAN ID to each of the configured subnets. To configure one or more VLANs, select [Network Configuration] --> VLAN from the navigation menu on the left. The VLAN Configuration screen appears.

The upper part of the screen is used to set up the VLAN type to be created. 1. Use the pull-down menu to select a VLAN Type for this switch. The two options available are User Based and Port Based. Port-based VLANs partitions traffic based on port on which the packet is received. The switch inspects each packet, extracts the port on which it was received (from control information provided by the driver) and processes the packet based on the port. The port is mapped to a subnet and each subnet is mapped to a single VLAN. The switch processes the packet based on this mapping. User-based VLAN traffic classification is performed only for Wireless traffic. The VLAN for a particular MU is identified when the MU authenticates itself with the RADIUS server using a user ID and password. The RADIUS server provides the VLAN ID corresponding to this MU and User ID information combination. The switch processes the packet based on the VLAN ID provided by the RADIUS server. For wired traffic, the classification as done in Port-based VLANs applies. 2. Use the pull-down menu to select a Trunk Port for the switch. Only the WAN port can be configured as the Trunk Port. 3. Enter the Default VLAN ID to be used for packets that do not have the VLAN tag inserted. The default VLAN ID must be one of the IDs assigned to the subnets if the VLAN Type is Port Based. If the VLAN Type is User Based, then the Default VLAN ID must be one from the Allowed VLANs list. 4. For each enabled Subnet, enter the VLAN ID.

3-16 WS2000 Wireless Switch System Reference Guide

5. Enter a list of allowed VLANs between 1 and 4094 in the Allowed VLANs box. The VLANs in this list will be allowed access through the WAN port. When entering multiple VLAN IDs, separate each ID with a comma. When entering a range of VLAN IDs, separate the starting and ending values with a “-”. 6. To enable filtering using IP, check the Enable IP Filtering check box. This option is only available only when Trunk Port is set to Wan. To add an IP filter, click IP Filtering button. The IP Filtering dialog appears. Set the appropriate filter and click Ok to close the dialog. 7. Click Ok on the VLAN Configuration screen to save changes. NOTE: Trunking VLANs through LAN ports is not available. For more information on trunking VLAN through the WAN port, and for assigning VLANs to WLANs, see Chapter 10, Trunking VLANs Through the WAN Port.

3.8 Configuring IP Filtering IP based filtering allows administrators to configure Incoming and Outgoing IP filtering policies on packets within the same Subnet / WLAN and between wired and wireless hosts. Filters can be set up based on IP Address or as a default rule for all IPs in a given direction Select [Network Configuration] --> IP Filtering from the left navigation menu.

1. Click the Add button to create a new filter in the table. The new filter can then be edited by clicking on the corresponding fields in the table. 2. Click on the Filter Name field and provide a name or edit an existing name for the filter. The Filter Name should be unique for each filter rule that is added. 3. Select a Protocol for the filter from the pull-down menu. The available protocols are: Transport

Protocol Independent Multicast (PIM) is a collection of multicast routing protocols, each optimized for a different environment. There are two main PIM protocols, PIM Sparse Mode and PIM Dense Mode. A third PIM protocol, Bi-directional PIM, is less widely used.

GRE

RSVP

The RSVP protocol is used by a host to request specific qualities of service from the network for particular application data streams or flows. RSVP is also used by routers to deliver quality-ofservice (QoS) requests to all nodes along the path(s) of the flows and to establish and maintain state to provide the requested service. RSVP requests will generally result in resources being reserved in each node along the data path.

IDP

Datagram Protocol (IDP) is a simple, unreliable datagram protocol, which is used to support the SOCK_DGRAM abstraction for the Internet Protocol (IP) family. IDP sockets are connection less and normally used with the sendto and recvfrom subroutines.

PUP

It is the first open protocol, named the Public Unitary Protocol (PUP protocol). It was developed to standardize communications protocol among controls manufacturers in the facility automation industry. This protocol is generally understood to form the basis of the current BACnet protocol, which has become popular of late.

EGP

The Exterior Gateway Protocol (EGP) is an exterior routing protocol used for exchanging routing information with gateways in other autonomous systems.

IPIP

IPIP is a protocol which is used to encapsulate an IP packet within another IP packet.

ESP

Encapsulating Security Protocol (ESP) is one of the two key components of IP Security Protocol (IPSec). The other key component is Authentication Header (AH), described in this section. ESP encrypts the payload of packets, and also provides authentication services. ESP can be used in transport mode, providing security between two end points. Also, ESP can be used in tunnel mode, providing security like that of a Virtual Private Network (VPN).

3.9 URL Filtering Use the URL Filtering screen to filter out access through HTTP to websites and services that do not meet the organizationâ&#x20AC;&#x2122;s access policies. URL Filtering works on the principles of maintaining a list of websites that are permitted access to, a set of keywords that are allowed or denied search permissions, a list of blacklisted websites, and a list of trusted IP addresses. This combination controls the HTTP access of any user behind the WS2000 to any resources on the internet. To use the URL Filtering feature, it must be enabled. By default, this feature is disabled enabling users unrestricted access. To enable the URL Filtering feature, Select [Network Configuration] --> URL Filtering from the left navigation menu.

1. To enable the URL Filtering feature, select Enable URL Filter feature. 2. If required, select Allow access on Reverse DNS reply failure. This feature is used to control access to restricted website when the user tries to use an IP address instead of the URL of the restricted website. In this scenario, the WS2000 performs a reverse DNS lookup for the IP address. The reply is received in the form of a URL and this URL is used to apply filtering rules. If the reverse DNS lookup does not return an URL, then this feature enables you to control access. 3. The default port for TCP access is port 80. If your configured port for TCP is other than port 80, then use the TCP Port field to configure it. URL Filter feature will filter any traffic through this port. 4. Use the Error Message field to display the message a user will see when a URL is blocked. To configure the filters to be used for URL Filter, select [Network Configuration] --> URL Filtering --> URL Parameters.

3-20 WS2000 Wireless Switch System Reference Guide

The URL Parameters screen contains four lists containing parameters used for URL filtering. There are four parameters: • White list – Use this list to provide access to specific websites. Websites in the white list are always allowed access. Up to 50 URLs can be configured. • Black list – Use this list to deny access to specific websites. Any attempt to access blacklisted websites are always denied. Up to 50 URLs can be configured. • Key word – Use this list to provide a list of keywords and the action to undertake when this keyword is encountered in any URL. By default, the action is deny. Change this to allow access when specific words are found in an URL. Up to 100 strings can be configured. • Trusted Hosts – These devices on the network are always allowed access. URL filtering is not performed on requests from these hosts. Up to 50 hosts can be configured. The URL filtering rules are checked in this order – Trusted Hosts, White List, Black List, Key word. Use the Add button under each list to add a row. Enter the required information directly into the list. Use the Del button under each list to remove a row. Select the row to delete and then click the Del button to remove.

3.10 Port Configuration Use the Port Configuration screen to enable or disable each of the 6 LAN ports and the WAN port. Use this screen to set their Auto Negotiation mode, speed and duplex states too. When the Auto Negotiation is enabled, the WS2000 determines the best operating speed and the duplex states for each port. To disable this, select Disable from the Auto Negotiation drop-down list. To select the operating speed for the port, select either 10 M or 100M from the Speed drop-down list for each port. This value should be selected based on your network configuration. To select the duplex mode for a port, select either Half or Full from the Duplex drop-down list. In half-duplex mode, traffic can pass only in one direction at a time. It can be either Rx or Tx. In full-duplex mode, traffic can pass in both direction simultaneously.

4-2 WS2000 Wireless Switch System Reference Guide

4.1 Configuring the WAN Interface A Wide Area Network (WAN) is a widely dispersed telecommunications network. In a corporate environment, the WAN port might connect to a larger corporate network. For a small business, the WAN port might connect to a DSL or cable modem to access the Internet. The administrator needs to enter the WAN configuration information. The WS2000 Wireless Switch includes one WAN port. In order to set up communications with the outside world, select [Network Configuration] --> WAN from the left menu. The following WAN configuration screen appears.

4.1.1 Configuring WAN IP Information 1. Check the Enable WAN Interface check box to enable a connection between the switch and a larger network or the outside world through the WAN port. 2. Enter the maximum transmission unit (MTU) size in the WAN MTU size field. This is the maximum permitted size for any packet that traverses the WAN interface. The default value is 1500. 3. Check This interface is a DHCP Client check box to enable Dynamic Host Configuration Protocol (DHCP) for the WAN connection. If This interface is DHCP Client is checked, the switch is limited to one WAN IP address. This choice is required when: • The host router or switch on the WAN is communicating with the WS 2000 Wireless Switch using DHCP. • The switch is interfacing with an Internet Service Provider (ISP) that uses DHCP addressing. NOTE: This setting is independent from the DHCP settings for the switch’s internal subnets.

WAN Configuration 4-3

4. It is not necessary to specify the IP Address or any of the other fields on the top section of this form when the WS 2000 Wireless Switch is set as a DHCP Client. The network host (router, switch, or modem) will provide these values each time it makes a connection with the switch. 5. If DHCP setting is not checked, fill in the information in this area. To find out the information to enter into these fields, contact the network administrator or the ISP that provided the cable modem or DSL router. All the fields below take standard IP addresses of the form xxx.xxx.xxx.xxx. • The IP Address refers to the IP address that the outside world will use to address the WS 2000 Wireless Switch. • Click the More IP Addresses button to specify additional static IP addresses for the switch. Additional IP addresses are required when users within the LAN need dedicated IP addresses, or when servers in the LAN need to be accessed (addressed) by the outside world. The pop-up window allows the administrator to enter up to eight WAN IP addresses for the switch. • The Subnet Mask is the mask used for the WAN. • The Default Gateway is the address of the device that provides the connection to the WAN (often a cable modem or DSL router). • The two DNS Server fields specify DNS addresses of servers that can translate domain names, such as www.motorola.com, into IP addresses that the network uses when passing information. The Secondary DNS Server acts as a backup to the Primary DNS Server, when the primary server is not responding.

4.1.2 Setting Up Point-to-Point over Ethernet (PPPoE) Communication

PPPoE provides the ability to connect a network of hosts through a simple device to a remote access concentrator. Many DSL providers require that their clients communicate using this protocol. The facility allows the ISP to control access, billing, and type of service provided to clients on a per-user or per-site basis. Check with the network administrator or ISP to determine whether to enable this feature, and, if so, find out the username and password required for authentication.

4-4 WS2000 Wireless Switch System Reference Guide

1. Check Enable in the PPP over Ethernet area to enable the PPPoE protocol for high-speed connections. 2. Enter the Username and Password required for authentication. The username and password is for the switchâ&#x20AC;&#x2122;s router to use when connecting to the ISP. When the Internet session starts, the ISP authenticates the username. 3. Set the Idle Time to an appropriate number. This number is the amount of time the PPPoE connection will be idle before it disconnects. The 10000 second default idle time is appropriate for most situations. 4. Check Keep Alive to instruct the switch to continue occasional communications over the WAN even when client communications to the WAN are idle. Some ISPs terminate inactive connections, while others do not. In either case, enabling Keep-Alive mode keeps the switchâ&#x20AC;&#x2122;s WAN connection alive, even when there is no traffic. If the ISP drops the connection after some idle time, the switch automatically reestablishes the connection to the ISP. 5. Select the appropriate WAN Authentication Type from the drop-down menu. Collect this information from the network administrator. Select between None, PAP, CHAP, or PAP or CHAP. CHAP

A type of authentication in which the person logging in uses secret information and some special mathematical operations to come up with a number value. The server he or she is logging into knows the same secret value and performs the same mathematical operations. If the results match, the person is authorized to access the server. One of the numbers in the mathematical operation is changed after every login, to protect against an intruder secretly copying a valid authentication session and replaying it later to log in.

PAP

An identity verification method used to send a user name and password over a network to a computer that compares the user name and password to a table listing authorized users. This method of authentication is less secure, because the user name and password travel as clear text that a hacker could read.

6. Set the PPPoE MSS Size. This is the Maximum Segment Size (MSS) and is used to negotiate the MTU (Maximum Transmission Unit) of a connection between two hosts. This limits the packet size to a specific maximum size. It is a good practice to set this value at 40-60 less than the desired MTU size to allow room for variable headers. 7. Set the PPPoE MTU Size. This is the Maximum Transmission Unit (MTU) and is the size of the largest PPPoE data unit that can traverse. This limits the packet size to a specific maximum. 8. Click the Apply button to save changes. 9. Once connected, the PPPoE State section will display the provided IP Address, Default Gateway, Primary DNS Server and Secondary DNS Server

4.2 Configuring the WS2000 Firewall The WS2000 Wireless Switch provides a secure firewall/Network Address Translation (NAT) solution for the WAN uplink. The firewall includes a proprietary CyberDefense Engine to protect internal networks from known Internet attacks. It also provides additional protection by performing source routing, IP unaligned timestamp, and sequence number prediction. The firewall uses a collection of filters to screen information packets for known types of system attacks. Some of the switchâ&#x20AC;&#x2122;s filters are always enabled, and others are configurable. To view or change the firewall settings, select [Network Configuration] --> Firewall from the left menu.

4.2.1 Disabling the Firewall The firewall can be enabled or disabled with one click. Check Disable Firewall if the filters should not be active. By default the firewall is enabled.

4.2.2 Setting the NAT Timeout 4.2.2.1 TCP Default Timeout The TCP Default Timeout field is used to set the NAT timeout value. The table below TCP Default Timeout field enables you to setup the NAT timeout values based on the Port and the protocol used. If the table has no rows, the timeout value entered in the TCP Default Timeout is used for all protocols and ports. In WS 2000 Wireless Switch, the NAT timeout configuration is global for any TCP/IP packet going through the firewall. This configuration restricts the type of UDP or TCP applications that can be used with WS2000.

4-6 WS2000 Wireless Switch System Reference Guide

Enter a default timeout value (in seconds) for the switch to use as the timeout value when no matching records are found in the NAT Timeout Table below. This is a global configuration for any TCP/IP packets going through firewall that don't match other values.

4.2.2.2 NAT Timeout Table In addition to the TCP Default Timeout setting, NAT timeout rules for specific TCP and UDP ports can be configured. To add rules to the NAT Timeout Table: 1. Click the Add button to add a row to the table. 2. Select a Transport method from the pull-down menu. Available options are: TCP

UDP

User Datagram Protocol (UDP) is mostly used for broadcasting data over the Internet. Like TCP, UDP runs on top of Internet Protocol (IP) networks. Unlike TCP/ IP, UDP/IP provides very few error recovery services and methods. UDP offers a way to directly connect, and then send and receive datagrams over an IP network.

3. Specify the Port number which the new timeout record will apply to. 4. Enter a Timeout value to specify the number of seconds before a NAT request is timed out by the switch's firewall. 5. Click the Apply button to save the changes to this page.

4.2.3 Configurable Firewall Filters The administrator can enable or disable the following filters. By default, all filters are activated. It is safe to turn the filters off if one of the following things is true: • The switch is on a completely isolated network with no access to the Internet and is therefore secure. • The switch is heavily loaded and a slight increase in performance outweighs the safety of the network. • Blocking these types of attacks would also block legitimate traffic on their network, although this scenario is highly unlikely. SYN Flood Attack Check

A SYN flood attack requests a connection and then fails to promptly acknowledge a destination host’s response, leaving the destination host vulnerable to a flood of connection requests.

Source Routing Check

A source routing attack specifies an exact route for a packet’s travel through a network, while exploiting the use of an intermediate host to gain access to a private host.

WAN Configuration 4-7

Winnuke Attack Check

A “Win-nuking” attack uses the IP address of a destination host to send junk packets to its receiving port. This attack is a type of denial of service (DOS) attack that completely disables networking on systems Microsoft Windows 95 and NT. Because this attack is only affective on older systems, it may not be necessary to enable this feature on a LAN with newer Microsoft Windows operating systems or with systems that have the appropriate “Winnuke” patches loaded.

FTP Bounce Attack Check

An FTP bounce attack uses the PORT command in FTP mode to gain access to arbitrary ports on machines other than the originating client.

IP Unaligned Timestamp Check

An IP unaligned timestamp attack uses a frame with the IP timestamp option, where the timestamp is not aligned on a 32-bit boundary.

Sequence Number Prediction A sequence number prediction attack establishes a three-way TCP Check connection with a forged source address, and the attacker guesses the sequence number of the destination host’s response. IP Spoof Attack Check

An IP Spoof Attack floods a destination host using an IP address that is not reachable on that interface.

Reset Attack Check

An attack where the TCP session is ended prematurely by an attacking host.

Sequence Number Out of Range Check

An attack which uses packet numbers which are out of the valid sequence range.

Mime Flood Attack Check

A MIME flood attack uses an improperly formatted MIME header in “sendmail” to cause a buffer overflow on the destination host. • Use the Max Header Length field to set the maximum allowable header length. Set this value to be at least 256 bytes. • Use the Max Headers field to set the maximum number of headers allowed. Set this value to be at least 12.

TCP FIN timeout

Enter a TCP FIN timeout value (in seconds) to determine how long the WS2K has to wait to receive a FIN before it closes the TCP connection.

4.2.4 Enabling NetBIOS ALG Use the NetBIOS ALG feature to allow hosts on WAN side of WS2000 to access Windows™ share folders with HOSTNAME instead of the IP address of the LAN PC. When this feature is enabled, the Host need not know the IP address of the LAN PC to access it. The LAN PC can be access by it’s name\share combination through Windows Explorer. For example, \\UserHome\JohnDoe. Configuring NetBIOS ALG access requires two steps. Most of the configuration for using NetBIOS must be performed on the client device on the WAN side. On the devices on the WAN side of WS2000, the following configuration must be performed.

4-8 WS2000 Wireless Switch System Reference Guide

Configuring WAN Hosts NOTE: These instructions are only valid for the Windows ™ operating system.

• The WAN hosts should map the HOSTNAME of the LAN side PC against the WAN IP address of the WS2000 in their c:\windows\system32\drivers\etc\lmhosts file. • WAN hosts should have their NetBIOS over TCP/IP enabled. To enable NetBIOS over TCP/IP on the WAN Hosts, do the following

1. Open the Local Area Connection Properties dialog for the WAN Host. 2. Click Internet Protocol (TCP/IP) to select it. 3. Click Properties button. The Internet Protocol (TCP/IP) Properties dialog box opens 4. Click the Advanced button located at the bottom right of the dialog box. The Advanced TCP/IP Settings dialog opens. 5. Select the WINS tab to enable it. 6. In the NetBIOS setting group, select the Default radio. You can also select the Enable NetBIOS over TCP/IP radio. 7. Click OK in each dialog box to close it. The LAN side PC can be accessed using this format: \\<host-name>\<shared-drive-name>

PCs on the LAN side need not be configured.

Configuring the WS2000 Navigate to the Firewall screen using [Network Configuration] --> Firewall in the left navigation menu tree. Click Enable NetBIOS ALG check box to select it.

4.2.5 Configuring the Application Layer Gateway (ALG) Use the Application Layer Gateway (ALG) to control how clients on the LAN side of the WS2000 accesses the WAN. 1. Navigate to the ALG - Configuration screen using [Network Configuration] --> Firewall --> ALG Configuration in the left navigation menu tree. The ALG - Configuration screen displays. 2. Click the Add button to add a new row in the Firewall Rules table. Only twenty (20) rules can be created in the Firewall Rules table. 3. Click the Src-IP column to display a dialog where you can enter the source IP address for the firewall rule. Similarly configure the IP address for the Dst-IP column too. 4. Click the Dst-Interface column to select the destination interface. The valid values are LAN and WAN. LAN indicates that the destination interface is on the LAN part of the WS2000. WAN indicates that the destination interface is located on the WAN side. 5. When WAN is selected as the destination, interface, select the NAT action to be performed. By default, the source IP address is translated to the IP defined as WAN1. To use any other defined IP, select the

WAN Configuration 4-9

appropriate one from the NAT drop down. â&#x20AC;&#x2DC;noneâ&#x20AC;&#x2122; indicates that the source IP address is sent without modification. This field has no effect if LAN is selected as the destination interface.

6. In the HTTP-ALG column, select Enable to allow the HTTP ALG check on traffic from the source IP to the Destination IP address. Select Disable otherwise. 7. Select Allow in the IPS column to enable the Intrusion Prevention System (IPS) to check the packets. Select Bypass to bypass the IPS check. The default is Allow. 8. To enable logging for this firewall rule, select Enable. Select Disable otherwise.

4-10 WS2000 Wireless Switch System Reference Guide

4.3 Configuring Intrusion Prevention System IP networks are vulnerable to security breaches by attackers exploiting known bugs in installed softwares. These attacks can originate from any host on the network or from devices outside the network. These attacks can either be intentional or un-intentional. If such an attack succeeds, the attacker could get access to vital and sensitive information stored on the host or can execute malicious code on the host or just prevent the host or hosts from functioning normally. Intrusion Prevention System (IPS) works alongside the firewall to detect vulnerability to such attacks. Any packet that flows through the network is examined by the IPS. Unlike the firewall which examines and blocks traffic based on IP addresses and ports, the IPS looks at different fields of the network traffic and then manages the traffic based on pre-defined patterns called “Signatures”. A signature is based on the protocol, source/destination ports, and the data pattern of the load. The signature also defines the action to be taken when an attack is detected. The action can be one of: • Drop the connection (in case of TCP connection) • Drop the packet • Generate an informative log message and then allow the packet through. Each and every packet entering or leaving the network is matched and the appropriate action taken. 1. IPS can be configured from the [Network Configuration] --> Firewall menu. The following screen appears.

Scroll to the bottom of the window to configure IPS settings.

WAN Configuration 4-11

2. To enable IPS, select the Enable IPS check box. 3. To enable the different signature categories that IPS uses, check the appropriate check box in the Signature Categories group. When checked, the IPS checks for intrusion on that protocol. The following IPS signature categories are available. TELNET

POP3

IMAP

NNTP

FTP

SNMP

TCPDNS

UDPDNS

TCPRPC

UDPRPC

HTTP

SMTP

TCPGEN

WAN Configuration 4-13

4.4 Configuring Network Address Translation (NAT) NAT provides the translation of an Internet Protocol (IP) address within one network to a different, known IP address within another network. One network is designated the private network, while the other is the public. NAT provides a layer of security by translating private (local) network addresses to one or more public IP addresses. For example, when an administrator wants to allow individuals on the WAN side access to a particular FTP or web server that is located on one of the LAN subnets but does not want to permit any other access, NAT is the appropriate solution. Generally NAT allows a single device such as a router to act as an agent between the public network and the private network to address issues related to IP address shortage. NAT here translates the WAN addresses to the external network addresses. 1. Select [Network Configuration] --> WAN --> NAT from the left menu. The following screen appears.

This screen displays the IP addresses specified in the WAN screen ([Network Configuration] --> WAN from the left menu). Up to eight WAN addresses can be associated with the switch. The NAT screen enables the administrator to set of the type of translation and port forwarding required. 2. For each of the addresses, the select the NAT type. • Select 1 to 1 from the pull-down menu to map a WAN IP address to a single local (subnet) IP address. This selection is useful in situations in which users require dedicated IP addresses or when publicfacing servers are connected to the switch. • Select 1 to Many from the pull-down menu to map a WAN IP address to a range of local IP addresses. Use this option when there are fewer public IP address on the WAN than there are users on the LAN. 1 to Many NAT allows a single IP address to handle traffic from multiple private LAN IP addresses. • Select None from the pull-down menu when the administrator sets up routable IP addresses (set on the [Network Configuration] --> Routing screen). 3. If the NAT type is 1 to 1, the Outbound Mappings field allows the administrator to specify a single IP Address. This address specifies the 1-to-1 mapping between the WAN IP address the specified LAN IP address.

4-14 WS2000 Wireless Switch System Reference Guide

4. If the NAT type is 1 to Many, the 1 to Many button in the adjacent Outbound Mappings field is active, allowing the administrator to specify address assignments for each subnet. If no translation should be done, none should be selected for the subnet.

5. Click the Port Forwarding button to display a sub-screen of port forwarding parameters for inbound traffic from the associated WAN IP address. When finished, click the Ok button to close the screen.

6. Click Add to add a new port forwarding entry and fill in the following fields. Name

Enter a name for the service that is being forwarded. The name can be any alphanumeric string and is used for easy identification of the service.

Transport

Use this pull-down menu to specify the transport protocol used in this service. The choices are ALL, TCP, UDP, ICMP, AH, ESP, and GRE.

Start Port / End Port

Enter the port or ports used by this service. To specify a single port, enter the port number in the Start Port field. To specify a range of ports, use both the Start Port and End Port fields to enter the port numbers. For example, enter 110 in the Start Port field and 115 in the End Port field.

IP Address

Enter the IP address to which the specified service is forwarded. This address must be within the specified NAT range for the associated WAN IP address.

WAN Configuration 4-15

Translation Port

Enter the port to which traffic is sent to after translation.

7. Click the Forward all unspecified ports to check box and then specify an IP address to enable port forwarding for incoming packets with unspecified ports. 8. Click the Apply button on the NAT screen to save changes.

4.5 Configuring Static Routes A router uses routing tables and protocols to forward data packets from one network to another. The WS2000 switch’s router manages traffic within the switch’s network, and directs traffic from the WAN to destinations on the switch-managed LAN. The WS2000 Network Management System provides the Router screen to view and set the router’s connected routes. To view this screen, select [Network Configuration] --> Router from the menu on the left.

The Route Table area of the screen displays a list of currently connected routes between the enabled subnets, the WAN, and the router. The information here is generated from settings applied on the Subnet and WAN screens. The destination for each subnet is its IP address. The subnet mask (or network mask) and gateway settings are those belonging to each subnet, or to the WAN in general. To make changes to the information in the Connected Routes information, go to the appropriate subnet screen (LAN --> <subnet name> or the WAN screen (WAN)).

4.5.1 Configuring the Default Gateway Interface The Default Gateway Interface allows you to specify which interface will be used as the default gateway for all unspecified routes on the WS2000. The available options are: None

Selecting this option will not set a Default Gateway Interface for unspecified routes.

WAN

Sets the WAN interface as the Default Gateway Interface for all unspecified routes.

4-16 WS2000 Wireless Switch System Reference Guide

Subnet 1

If Subnet 1 is enabled, sets it as the Default Gateway Interface for all unspecified routes.

Subnet 2

If Subnet 2 is enabled, sets it as the Default Gateway Interface for all unspecified routes.

Subnet 3

If Subnet 3 is enabled, sets it as the Default Gateway Interface for all unspecified routes.

Subnet 4

If Subnet 4 is enabled, sets it as the Default Gateway Interface for all unspecified routes.

Subnet 5

If Subnet 5 is enabled, sets it as the Default Gateway Interface for all unspecified routes.

Subnet 6

If Subnet 6 is enabled, sets it as the Default Gateway Interface for all unspecified routes.

default

Sets the gateway to default for all unspecified routes.

4.5.2 Creating User Defined Routes The User Defined Routes area of the screen allows the administrator to view, add or delete internal static (dedicated) routes, and to enable or disable routes that are generated using the Routing Information Protocol (RIP). If RIP is enabled, this table can also include routes that RIP generates. This table also includes internal static routes that the administrator adds. Internal static routes are dedicated routes for data that travels from the WAN, through the switch, and to a specified subnet. Such routes are supplemental to the default routes already set up for each of the subnets. 1. Click the Add button to create a new table entry. 2. Specify the destination IP address, subnet mask, and gateway information for the internal static route. 3. Select an enabled subnet from the Interface columnâ&#x20AC;&#x2122;s drop-down menu to complete the table entry. Information in the Metric column is automatically generated, and is used by router protocols to determine the best hop routes. 4. Click the Apply button to save changes.

4.5.3 Setting the RIP Configuration Routing Information Protocol (RIP) is an interior gateway protocol that specifies how routers exchange routing-table information. The Routing screen also allows the administrator to select the type of RIP and the type of RIP authentication used by the switch. To set or view the RIP configuration, click the RIP Configuration button. The following subscreen appears.

WAN Configuration 4-17

1. Select the RIP Type from the pull-down menu to be one of the following values. No RIP

Depending on the RIP Direction setting, the No RIP option partially or completely disallows the switch’s router from exchanging routing information with other routers. Routing information may not be appropriate to share, for example, if the switch manages a private LAN.

RIP v1

RIP version 1 is a mature, stable, and widely supported protocol. It is well suited for use in stub networks and in small autonomous systems that do not have enough redundant paths to warrant the overhead of a more sophisticated protocol.

RIP v2 (v1 compat)

RIP version 2 (compatible with version 1) is an extension of RIP v1’s capabilities, but it is still compatible with RIP version 1. RIP version 2 increases the amount of packet information to provide a simple authentication mechanism to secure table updates.

RIP v2

RIP version 2 enables the use of a simple authentication mechanism to secure table updates. More importantly, RIP version 2 supports subnet masks, a critical feature that is not available in RIP version 1. This selection is not compatible with RIP version 1 support.

2. Select a routing direction from the RIP Direction drop-down menu. Both (for both directions), Rx only (receive only), and TX only (transmit only) are available options. 3. If RIP v2 or RIP v2 (v1 compat) is the selected RIP type, the RIP v2 Authentication area of the screen becomes active. Select the type of authentication to use from the Authentication Type drop-down menu. Available options are: None

This option disables the RIP authentication.

Simple

This option enable RIP version 2’s simple authentication mechanism. This setting activates the Password (Simple Authentication) field.

MD5

This option enables the MD5 algorithm for data verification. MD5 takes as input a message of arbitrary length and produces a 128-bit fingerprint. The MD5 algorithm is intended for digital signature applications, in which a large file must be compressed in a secure manner before being encrypted with a private (secret) key under a public-key cryptographic system. The MD5 setting activates the RIP v2 Authentication settings for keys (below).

4-18 WS2000 Wireless Switch System Reference Guide

4. If the Simple authentication method is selected, specify a password of up to 15 alphanumeric characters in the Password (Simple Authentication) field. 5. If the MD5 authentication method is selected, fill in the Key #1 and Key #2 fields. Type in any numeric value between 0 and 256 into the MD5 ID field. Type in any string consisting of 16 alphanumeric characters into the MD5 Auth Key field. 6. Click the Ok button to return to the Routing screen.

WAN Configuration 4-19

4.6 Configuring a Virtual Private Network (VPN) VPNs are IP-based networks that use encryption and tunneling to give users remote access to a secure LAN. In essence, the trust relationship is extended from one LAN across the public network to another LAN, without sacrificing security. A VPN behaves similarly to a private network; however, because the data travels through the public network, three types of security mechanisms are required: confidentiality, integrity, and authentication. • Confidentiality (through public-key or secret-key cryptology) ensures the privacy of information being exchanged between communicating parties. • Integrity ensures that information being transmitted over the public Internet is not altered in any way during transit (by using hash codes, message authentication codes, or digital signatures). • Authentication (with password authentication or digital signatures) ensures the identity of all communicating parties. A diagram of a typical VPN situation is shown below, where there is a VPN tunnel created between two WS2000 switches across the WAN. The diagram shows the settings for both switches.

The WS2000 Network Switch provides VPN technology with a variety of security and setup options. Select [Network Configuration] --> WAN --> VPN from the left menu to create a VPN tunnel.

4-20 WS2000 Wireless Switch System Reference Guide

Use the Auto Initiate Interval to set the interval when the status of all tunnels are checked. This is a global configuration which is common for all the tunnels and is valid only when Auto Initiate is enabled. Normally, when the tunnelâ&#x20AC;&#x2122;s life time gets over, its gets disconnected. This feature ensures that the tunnel is automatically initiated once its life time is over.

4.6.1 Creating a VPN Tunnel 1. Click the Add button to create a VPN tunnel. The lower portion of the screen, which then appears, is used to configure VPN tunneling.

2. Type a name for the tunnel into the Tunnel Name field. Use a name that indicates the role and purpose of the tunnel.

WAN Configuration 4-21

3. Select the subnet that will be the local end of the tunnel from the Local Subnet menu. 4. Specify the IP address to use for the local WAN (Local Wan IP), which should be one of the (up to) eight IP addresses specified in the WAN screen. 5. Specify the IP address for the Remote Subnet along with its subnet mask (Remote Subnet Mask). Remote Subnet is the remote end of the VPN tunnel. This field accepts 0.0.0.0 as the remote subnet IP address. 6. Specify the IP address for the Remote Gateway. 7. Click the Apply button to save the changes.

4.6.2 Setting Up VPN Security The WS 2000 Wireless Switch provides several different options for VPN security, all based upon encryption key exchange: 1. Manual Key Exchange uses the Manual Key Settings screen to specify the transform sets that will be used for VPN access. A transform set is a combination of security protocols and algorithms that are applied to IPSec protected traffic. A transform set specifies one or two IPSec security protocols (either AH, ESP, or both) and specifies which algorithms to use with the selected security protocol. During security association (SA) negotiation, both gateways agree to use a particular transform set to protect the data flow. If you specify an ESP protocol in a transform set, you can specify just an ESP encryption transform or both an ESP encryption transform and an ESP authentication transform. When a particular transform set is used during negotiations for IPSec SAs, the entire transform set (the combination of protocols, algorithms, and other settings) must match the transform set at the remote end of the gateway. 2. Automatic Key Exchange enables the WS 2000 Wireless Switch to automatically set encryption and authentication keys for VPN access. The Auto Key Settings subscreen provides the means to specify the type of encryption and authentication, without specifying the keys. 3. Internet Key Exchange (IKE) protocol is an IPSec standard protocol used to ensure security for VPN negotiation, and remote host or network access. IKE provides an automatic means of negotiation and authentication for communication between two or more parties. IKE manages IPSec keys automatically for the parties. Each of these options requires some configuration, as described below.

4.6.3 Configuring Manual Key Exchange 1. Select the Manual Key Exchange radio button. 2. Click the Manual Key Settings button to specify the encryption method and the following screen appears. The setup process requires specifying both the authentication and the encryption methods and keys.

4-22 WS2000 Wireless Switch System Reference Guide

3. Select the authentication and anti-replay method you wish to use for the tunnel from the AH Authentication menu. None

This option selects the Advanced Encryption Standard algorithm in use with 192-bit (48character hexadecimal) keys.

AES 256-bit

This option selects the Advanced Encryption Standard algorithm in use with 256-bit (64character hexadecimal) keys.

8. Provide keys for both Inbound ESP Encryption Key and Outbound ESP Encryption Key. The length of the keys is mandated by the selected encryption algorithm. These keys must match the opposite keys at the remote gateway. The outbound key here must match the inbound key at the remote gateway, and the inbound key here must match the outbound key at the remote gateway. 9. If ESP with Authentication is enabled, an authentication algorithm must be selected to be used with ESP from the ESP Authentication Algorithm menu. MD5

Enables the Message Digest 5 algorithm, which requires 128-bit (32-character hexadecimal) authentication keys.

SHA1

Enables Secure Hash Algorithm 1, which requires 160-bit (40-character hexadecimal) keys.

10.If ESP with Authentication is enabled, specify both the Inbound and Outbound ESP Authentication Keys. 11.Provide two (up to) eight-character hexadecimal values used to identify the inbound and outbound security association created by the encryption algorithm. These values must match the reciprocal inbound/outbound SPI values configured on the remote security gateway, so the local inbound key must match the remote outbound key, and so on. This value should also be unique across all tunnels on the system. 12.Select Ok to return to the VPN screen.

4-26 WS2000 Wireless Switch System Reference Guide

3. Select the Operation Mode for IKE. The Phase I protocols of IKE are based on the ISAKMP identityprotection and aggressive exchanges. IKE main mode refers to the identity-protection exchange, and IKE aggressive mode refers to the aggressive exchange. Main

This is the standard IKE mode for communication and key exchange.

Aggressive

Aggressive mode is faster and less secure than Main mode. Identities are not encrypted unless public key encryption is used. The Diffie-Hellman group cannot be negotiated; it is chosen by the initiator. Also, the authentication method cannot be negotiated if the initiator chooses to use public key encryption.

4. Select the type of ID to be used for the WS2000 end of the tunnel from the Local ID Type menu. IP

Select this option if the local ID type is the IP address specified as part of the tunnel.

FQDN

Select this item if the local ID type is a fully qualified domain name (such as sj.symbol.com). The setting for this field does not have to be fully qualified, it just must match the setting of the field for the Certificate Authority.

UFQDN

Select this item if the local ID type is a user unqualified domain name (such as johndoe@symbol.com). The setting for this field does not have to be unqualified, it just must match the setting of the field of the Certificate Authority.

5. If FQDN or UFQDN are selected, specify the data (either the qualified domain name or the user name) in the Local ID Data field. 6. Repeat steps 4 and 5 for the Remote ID Type and Remote ID Data fields. 7. Choose the authentication mode to be used with the IKE algorithm from the IKE Authentication Mode menu. Pre-shared key This option requires that you specify an authentication algorithm and passcode to be used during authentication. RSA Certificates

4.6.6 VPN: Frequently Asked Questions WARNING! Disclaimer: Using a VPN connection over the WAN interface is subject to the limitations of your Internet Service Provider.

4.6.6.1 My tunnel works fine when I use the Subnet Access page to configure my firewall. Now that I use Advanced Subnet Access, my VPN no longer works. What am I doing wrong? VPN requires certain packets to be passed through the firewall. Subnet Access automatically inserts these rules for you when you do VPN. Using Advanced Subnet Access requires the following rules to be in effect for each tunnel. An allow inbound rule: Src

Dst

Transport

ANY

Src port

1:65535

Dst port

1:65535

Rev NAT

None

4-28 WS2000 Wireless Switch System Reference Guide

An allow outbound rule: Src

Dst

Transport

ANY

Src port

1:65535

Dst port

1:65535

Rev NAT

None

For IKE, an allow inbound rule: Src

Dst

Transport

UDP

Src port

1:65535

Dst port

500

Rev NAT

None

These rules must be above (higher in priority than) any default or other rules that would process these packets differently.

4.6.6.2 Do I need to add any special routes on the WS2000 switch to get my VPN tunnel to work? No. Packets for VPN are tunneled directly to the Remote VPN gateway. As long as a route exists to the Remote VPN gateway, no other routes are required. Clients, however, might need extra routing information to tell them to use the WS2000 switch as the gateway to reach the remote subnet. This is only required if the clients are not using the WS2000 switch as their default gateway.

4.6.6.3 Can I setup the WS2000 Wireless Switch so that clients can both access the WAN normally and use the VPN when talking only to specific networks? Yes. Only packets that are going from the defined local subnet to the remote subnet will be send through the VPN tunnel. All other packets will be handled by whatever firewall rules are set.

WAN Configuration 4-29

4.6.6.4 How do I specify which certificates to use from the WS2000 certificate manager to be used for an IKE policy? When generating a certificate to be used with IKE, you must use one of the following fields: IP address, Domain Name, or E-mail address. Also make sure that you are using NTP when attempting use the certificate manager. Certificates are time sensitive. On the IKE configuration page, Local ID type refers to the way that IKE selects a local certificate to use. IP tries to match the local WAN IP to the IP addresses specified in a local certificate. FQDM tries to match the user entered local ID data string to the domain name field of the certificate. UFQDM tries to match the user entered local ID data string to the email address field of the certificate. Remote ID type refers to the way you identify an incoming certificate as being associated with the remote side. IP tries the match the remote gateway IP to the IP addresses specified in the received certificate. FQDM tries to match the user entered remote ID data string to the domain name field of the received certificate. UFQDM tries to match the user entered remote ID data string to the email address field of the received certificate.

4.6.6.5 I am using a direct cable connection between by two VPN gateways for testing and cannot get a tunnel established, yet it works when I setup them up across another network or router. What gives? The packet processing architecture of the WS2000 VPN solution requires a WAN default gateway to work properly. When connecting two gateways directly, you really do not need a default gateway when the two addresses are on the same subnet. As a work around, you can point the WS2000 switchâ&#x20AC;&#x2122;s WAN default gateway to be the other VPN gateway, and vice-versa.

4.6.6.6 My WS2000 switch is a DHCP client on my WAN interface. How can I setup a tunnel without knowing my WAN IP address? First of all, one end of a VPN tunnel must have a static IP address. Assuming the other end of your VPN tunnel has a static IP, here is how you configure your WS2000 switch to use a DHCP WAN address with VPN. 1. Your VPN tunnel entry must have the Local WAN IP set to 0.0.0.0. 2. If you are using the IKE, the Local ID type (and corresponding Remote ID type on the other end) cannot be set to IP, since the IP address is not known.

4-30 WS2000 Wireless Switch System Reference Guide

4.6.6.7 How can I setup the WS2000 switch to accept VPN tunnels from gateways that have a DHCP WAN address? To accept a VPN tunnel from a unknown (DHCP) address, the WS2000 Wireless Switch operates in what is called responder-only mode. That is, it cannot initiate the VPN connection. It can only wait for a VPN connection to come in. Clients behind a responder-only cannot connect to the remote subnet until the remote subnet has connected to them. To setup responder-only mode, set the Remote Gateway to 0.0.0.0. If you are using IKE the following restrictions are in place: • Remote ID type cannot be IP. We do not know the IP of the remote since it is DHCP. • IKE Authentication Mode cannot be set to PSK if IKE mode is set to Main Mode. • You may not use xAuth for this tunnel.

4.6.6.8 I have two WS2000 switches and both have DHCP WAN addresses. Is there any possible way to open a VPN tunnel between them? Yes, but the configuration for each tunnel will need to change anytime a WAN IP lease expires. You can make this work temporarily by performing the following steps: 1. Set 0.0.0.0 as the local WAN IP for each gateway. 2. Configure the opposite WS2000 switch’s current DHCP address as the Remote Gateway. This is the field that needs to change every time the DHCP addresses change. 3. If using IKE, you cannot use ID type IP for either Local or Remote ID types.

4.6.6.9 I have set up my tunnel and the status still says “Not Connected.” What should I do now? VPN tunnels are negotiated on an as-needed basis. If you have not sent any traffic between the two subnets, the tunnel will not be established. Once a packed is sent between the two subnets, the VPN tunnel setup will occur.

4.6.6.10 I still can’t get my tunnel to work after attempting to initiate traffic between the 2 subnets. What now? Here are some troubleshooting tips: 1. Verify that you can ping each of the remote gateway IP addresses from clients on either side. Failed pings can indicates general network connection problems. 2. Pinging the internal gateway address of the remote subnet should run the ping through the tunnel as well. Allowing you to test even if there are no clients on the remote end. 3. Verify that your WAN IP address is not DHCP. VPN requires a static WAN IP address to work.

4.7 Configuring Content Filtering Content filtering allows system administrators to block specific commands and URL extensions from going out through the WS2000 switchâ&#x20AC;&#x2122;s WAN port. This feature allows blocking up to 10 files or URL extensions and allows blocking of specific outbound HTTP, SMTP, and FTP requests. To configure content filtering, select [Network Configuration] --> WAN --> Content Filtering from the left menu.

1. Select the type of blocking for outbound HTTP requests. Check one or both of the options: Web Proxy

This selection blocks the use of web proxies by clients.

ActiveX

This selection blocks all outgoing ActiveX requests by clients.

2. Enter the Outbound URL extensions to block. Do this by typing one URL extension or file name (filename.ext) per line. Use an asterisk (*) as a wildcard in place of the filename to block all files with a specific extension (for example *.exe). 3. Simple Mail Transport Protocol (SMTP) is the Internet standard for host-to- host mail transport. SMTP generally operates over TCP on port 25. SMTP filtering allows the blocking of any or all outgoing SMTP commands.Choose which SMTP commands to block from the list, by checking those commands to block. HELO

(Hello) This command is used to identify the SMTP sender to the SMTP receiver.

MAIL

(Mail) This command initiates a mail transaction where mail data is delivered to one or more mailboxes on the local server.

RCPT

(Recipient) This command is used to identify a recipient of mail data.

DATA

(Data) This command tells the SMTP receiver to treat the following information as mail data from the sender.

QUIT

(Quit) This command tells the receiver to respond with an OK reply and then terminate communication with the sender.

SEND

(Send) This command initiates a mail transaction where mail is sent to one or more remote terminals.

4-32 WS2000 Wireless Switch System Reference Guide

SAML

(Send and Mail) This command initiates a mail transaction where mail data is sent to one or more local mailboxes and remote terminals.

RESET

(Reset) This command cancels the current mail transaction and informs the recipient to discard any data sent during this transaction.

VRFY

(Verify) This command asks the receiver to confirm that the specified argument identifies a user. If the argument does identify a user the full name and fully qualified mailbox is returned.

EXPN

(Expand) This command asks the receiver to confirm that a specified argument identifies a mailing list. If the argument does identify a mailing list the membership list of that mailing list is returned.

4. Specify the outbound FTP actions that should get blocked by checking the FTP action to block. File Transfer Protocol (FTP) is the Internet standard for host-to-host file transport. FTP generally operates over TCP on port 21. Storing Files

Blocks the request to transfer files sent from the client across the switch’s WAN port to the FTP server.

Retrieving Files

Blocks the request to retrieve files sent from the FTP server across the switch’s WAN port to the client.

4.8 Configuring DynDNS The WS2000 Wireless Switch provides support for using the DynDNS service. Dynamic DNS is a feature offered by www.dyndns.com which allows the mapping of domain names to dynamically assigned IP addresses. When the dynamically assigned IP address of a client changes that new IP address is sent to the DynDNS servers and traffic for the specified domain(s) is routed to the new IP address. To view or change the DynDNS settings, select [Network Configuration] --> WAN --> DynDNS from the left menu.

4.8.1 Enabling and Configuring DynDNS 1. Click Enable check box to activate DynDNS configuration. Enabling Dyn DNS will allow domain name information to be updated when the IP address associated with that domain changes. In order for changes to go through, a username, password, and hostname must be specified in the fields below. 2. Enter a your DynDNS Username for the DynDNS account you wish to use for the WS2000. 3. Enter your Password for the DynDNS account you wish to use for the WS2000. 4. Enter your Hostname for the DynDNS account you wish to use for the WS2000. 5. Click Apply button to save changes.

4.8.2 Updating DynDNS Click the Update DynDNS button to update the WS2000's current WAN IP address with the DynDNS service. After you have clicked the Update DynDNS button, click the Show Update Response button to open a dialogue which displays the hostname, IP address and any messages received during the update from the DynDNS servers.

Wireless Configuration 5-3

5.1 Enabling Wireless LANs (WLANs) The WS 2000 Wireless Switch works in either a wired or wireless environment; however, the power of the switch is associated with its support of wireless networks. To use the wireless features of the switch, the administrator needs to enable one, two, or three wireless LANs (WLANs). To start the WLAN configuration process, select the [Network Configuration] --> Wireless item from the left menu. The following Wireless summary screen appears.

5.1.1 WLAN Summary

The top portion of the window displays a summary of the WLANs that are currently defined. This is the screen in which the administrator can enable or disable a WLAN. By default, eight WLANs will be listed WLAN1, WLAN2, WLAN3, WLAN4, WLAN5, WLAN6, WLAN7 and WLAN8. However, only WLAN1 will be enabled. 1. To enable a WLAN, check the check box to the left of the WLAN name. When the administrator enables one of the WLANs, the name of an enabled WLAN shows up as an item on the list of WLANs that reside under Wireless menu tree on the left (after clicking the Apply button). When an administrator disables a WLAN, it disappears from the menu tree. A WLAN cannot be configured unless it is enabled. 2. To enable a WLAN as a hotspot, check the box marked Hotspot next to the WLAN(s) you wish to use as a hotspot. To configure hotspot settings see Chapter 8, Configuring HotSpot.

5-4 WS2000 Wireless Switch System Reference Guide

The screen also displays the following information: 1. By default, the switch assigns consecutive Extended Service Set Identification (ESSIDs). This is the name that users will see when accessing the wireless network. The ESSID can be given any recognizable alphanumeric string up to 32 characters in length. 2. The Subnet field displays the subnet assigned to the WLAN. 3. The Access Ports Adopted field displays the Access Port numbers adopted by this WLAN. The following configuration for each WLAN can be performed from the [Network Configuration] ->Wireless --> <WLANx> screen. 1. Assign the enabled WLANs descriptive names. The administrator can change the name of any of the WLANs in the Name field. This change will affect several other screens and the interface will change the name in the left menu tree. 2. By default, the switch assigns consecutive Extended Service Set Identification (ESSIDs). This is the name that users will see when accessing the wireless network. The ESSID can be given any recognizable alphanumeric string up to 32 characters in length. 3. An icon of a lock will appear under the Security heading if any wireless encryption or authentication is enabled for the WLAN. The current settings for the associated Subnet and adopted Access Ports are also displayed on this screen; however, the screen associated with each WLAN (under [Network Configuration] --> Wireless) is where the settings and rules for adopting Access Ports can be modified.

5.1.1.1 WEP Shared Mode The WEP Shared Mode check box enables WEP Shared secret key authentication. IEEE802.11 defines two types of Authentication service: Open System and Shared Key. In Shared Key authentication service prior to Association phase STAs need to authenticate itself using the shared secret key. This authentication scheme is only available if the WEP option is implemented. The required secret, shared key is presumed to have been delivered to participating STAs via a secure channel that is independent of IEE802.11.

5.1.1.2 SIP CAC Mode The SIP CAC Mode check box enables or disables the SIP Call Admission Control feature which when used in conjunction with compatible VoIP hardware will test for network congestion before allowing VoIP calls to connect. This can help ensure call quality and connection when making VoIP calls.

5.1.1.3 HotSpot Credential Caching Mode The HotSpot Credential Caching Mode check box enables the administrator to cache hotspot user credentials on the WS2000. This feature is not enabled by default. The administrator has to explicitly enable this feature.

5.1.1.4 STP on Mesh Link The STP on Mesh Link check box enables Spanning Tree Protocol (STP) on mesh links. This is different from enabling STP from the [Network Configuration] --> LAN screen. Selecting STP from the [Network Configuration] --> LAN screen, enables STP on the wired side of the WS2000. Enabling STP on Mesh Link enables STP on the wireless side of WS2000. By default, all ports of WS2000 Wireless Switch go through the STP convergence states whenever configuration changes were made. In scenarios where, on a wired bridge port, the L2 switch to which this WS2000 was connected to had STP BPDU guard enabled, would cause the WS2000 to go offline. This was

Wireless Configuration 5-5

mitigated by allowing enabling/disabling of STP on the wired side. However, STP was not configurable on the wireless side. So, if there was a configuration change, all the MUs got disassociated and remained so till the STP processing was complete. Moreover, by design, the radio ports on the WS2000 were deleted and re-created every time a configuration change was made. The would force STP convergence steps on the new radio port and delay MUs re-association. STP on Mesh Link is enabled by default. Disable this option to allow MUs to associate or re-associate faster. However, before disabling STP on Mesh Link, consider the implications of creation of loops in the topology.

5.1.1.5 MU Inactivity Timeout Enter the duration of inactivity after which inactive MUs are disassociated from the WLAN. The default value is 10 minutes.

5.1.1.6 Hotspot Inactivity Timeout Enter the duration of inactivity for a user after which the user is timed out from the hotspot. The default value is 20 minutes and the maximum timeout value is 1440 minutes (1 day).

5.1.2 AP Adoption Configuration The AP Adoption Configuration screen allows for setting up default Access Port adoption rules as well as a deny list to prevent the adoption of specific Access Ports.

5.1.2.1 AP Deny List The AP Deny List allows you to prevent individual Access Ports from associating with the switch. For each Access Port you wish to deny, click the Add button and enter the deviceâ&#x20AC;&#x2122;s MAC Address into the field provided. To add an AP to the AP Deny List: 1. Click the Add button located below the AP Deny List table. A new row will be added to the table. 2. Enter the MAC Address of the Access Port you wish to deny. 3. Click the Apply button to save the changes. Up to 12 entries can be made to this list.

5.1.2.2 Access Port Radio Adoption List Use this list to adopt detected Access Ports and to assign them to a particular WLAN. The switch can adopt up to six Access Ports at a time, but the list of allowed Access-Port addresses (displayed in this area) can exceed six in number. A dual-radio 802.11a/b Access Port counts as one Access Port with respect to the maximum allowed; however, each radio will be listed as a separate Access Port. This adoption list identifies each Access Port by its Media Access Control (MAC) address. This address is the Access Portâ&#x20AC;&#x2122;s hard-coded hardware number that is printed on the bottom of the device. An example of a MAC address is 00:09:5B:45:9B:07. 1. To adopt an Access Port, click the Add button to add a new criteria line to the table.

5-6 WS2000 Wireless Switch System Reference Guide

2. Specify the following fields: Field

Description

Start MAC

This field contains the lowest value in a range of MAC addresses that will use this particular adoption criteria. To specify a single MAC address instead of a range, enter it in this field as well as the End MAC field.

End MAC

This field contains that highest number in a range of MAC addresses that will use this particular adoption criteria. If this value is empty, the Access Port adopted by this criteria must match the Start MAC field exactly.

WLAN columns

The next eight columns are associate with the eight WLANs that are shown in the upper portion of the screen. To the left, specify a range of Access Port MAC address for adoption. Then, click the check boxes of the WLANs that need to adopt the Access Ports in the specified range.

NOTE: The default setting for the switch has both the Start MAC and End MAC addresses set to â&#x20AC;&#x153;ANYâ&#x20AC;?, and all enabled WLANs checked. This setting allows all the WLANs to adopt any Access Port that it detects, automatically. 3. Up to 20 entries can be added to the Access Port Adoption list. Click the Apply button to save changes.

Wireless Configuration 5-7

5.2 Configuring Wireless LANs The [Network Configuration] --> Wireless window (covered in Enabling Wireless LANs (WLANs)) is where WLANs are enabled; however, the [Network Configuration] --> Wireless --> <WLAN name> screen is where the administrator configures each WLAN, after it is enabled. The screen is titled with the name of the WLAN.

Within the WLAN window, the administrator can modify both standard and advanced configuration features of the WLAN. Field

Description

Name

Rename the WLAN in this field, if desired. Character spaces are allowed. This change affects several other screens and the interface will also change the name in the left menu tree. Motorola recommends the use of descriptive names for WLANs.

ESSID

Specify an Extended Service Set Identification (ESSID) for the WLAN. The ESSID is a alphanumeric string up to 32 characters. Its purpose is to identify one or more Access Ports that are associated with the WLAN.

Subnet

This field provides a pull-down menu of the enabled subnets. Select the subnet to associate with the current WLAN.

VLAN

This is a read-only field which displays the VLAN ID of the VLAN associated with this WLAN. This setting can be changed on the VLAN Configuration screen.

5.2.1 Configuring Advanced WLAN Settings The lower section of the WLAN screen provides several settings that the administrator might need to modify; however, the default settings are usually sufficient for most installations.

5-8 WS2000 Wireless Switch System Reference Guide

1. Check the Disallow MU to MU Communications box to enable a communication block between mobile units (MUs) using this WLAN. Such communication might be a security issue, for example, on a corporate network. Leave this check box unchecked (default setting) to allow MU-to-MU communications on this WLAN. 2. Check the Answer Broadcast ESS check box to enable adopted Access Ports to transmit the WLAN’s Extended Service Set Identification (ESSID). The purpose of allowing WLANs to answer the broadcast ESS is to identify Access Ports that are associated with the WLAN. This might be appropriate, for example, in a customer environment, such as a “hot spot.” Disable this option if broadcasting the WLAN’s ESSID poses a security risk, such as with a private, corporate network. The default setting is unchecked. 3. Check the Secure Beacon check box to disallow the Access Port from broadcasting its ESSID in its beacons. This is to prevent intruders from becoming members of the WLAN. Use this for a more secure network. 4. Click the Apply button to save changes. For more advanced WLAN settings see Quality of Service Configuration or Configuring Wireless LAN Security later in this chapter.

5.3 Configuring Wireless LAN Security The WS 2000 Wireless Switch allows the administrator to set the type and level of security for each WLAN. These security measures do not control communications from the WAN; instead, they control communication from the clients within the WLAN. In the [Network Configuration] --> Wireless --> <WLAN name> --> <WLAN Name> Security screen, the administrator can set the user authentication method and the encryption method, as well as define a set of rules that control which MUs can communicate through the WLAN.

Wireless Configuration 5-9

5.3.1 Selecting the Authentication Method

The authentication method sets a challenge-response procedure for validating user credentials such as username, password, and sometimes, secret-key information. The WS 2000 Wireless Switch provides two methods for authenticating users: 802.1x EAP and Kerberos. The administrator can select between these two methods. If WLAN security is not an issue, the administrator can decide not to enable authentication (No Authentication), because authentication protocols create overhead for the switchâ&#x20AC;&#x2122;s processor.

5.3.2 Configuring 802.1x EAP Authentication The IEEE 802.1x is an authentication standard that ties EAP to both wired and wireless LAN applications. EAP provides effective authentication with or without IEEE 802.1x Wired Equivalent Privacy (WEP) encryption, or with no encryption at all. EAP supports multiple authentication measures. It requires that the site have an authentication (Remote Dial-In User Service, or RADIUS) server on the wired side of the Access Port. All other packet types are blocked until the authentication server verifies the clientâ&#x20AC;&#x2122;s identity. To set up 802.1x EAP authentication: 1. On the [Network Configuration] --> Wireless --> <WLAN Name> --> <WLAN Name> Security screen, select the 802.1x EAP radio button to enable the 802.1x Extensible Authentication Protocol (EAP). The 802.1x EAP Configuration button is enabled. 2. Click the 802.1x EAP Configuration button to display a sub-screen for specific authentication settings.

5-10 WS2000 Wireless Switch System Reference Guide

3. The administrator is required to specify the RADIUS Server Address of a primary RADIUS server for this type of authentication to work. Providing the IP address of a secondary server is optional. The secondary server acts as a failover server if the switch cannot successfully contact the primary server. 4. Specify the port on which the primary RADIUS server is listening in the RADIUS Port field. Optionally, specify the port of a secondary (failover) server. Older RADIUS servers listen on ports 1645 and 1646. Newer servers listen on ports 1812 and 1813. Port 1645 or 1812 is used for authentication. Port 1646 or 1813 is used for accounting. The ISP or a network administrator can confirm the appropriate primary and secondary port numbers. 5. The administrator can specify a RADIUS Shared Secret for authentication on the primary RADIUS server. Shared secrets are used to verify that RADIUS messages (with the exception of the AccessRequest message) are sent by a RADIUS-enabled device that is configured with the same shared secret. The shared secret is a case-sensitive string that can include letters, numbers, or symbols. Make the shared secret at least 22 characters long to protect the RADIUS server from brute-force attacks. 6. To use the local RADIUS server as the primary server, click the Use Local Radius button. 7. Specify the interface to bind the RADIUS client to. Select the interface to bind the RADIUS client from the drop down list under each authentication server. With this feature, it is now possible to authenticate a wireless (802.1x authentication) user with a RADIUS server through a VPN tunnel. If the RADIUS server is on a network accessible through a VPN tunnel, then the tunnel must be configured. The bind interface should be the same as the Local Subnet configured for the VPN tunnel.

Reauthentication Settings 8. Check the Enable Reauthentication check box to enable this authentication method. 9. In the Period field, set the EAP reauthentication period to match the appropriate level of security. A shorter time interval (~30 seconds or longer) provides tighter security on this WLANâ&#x20AC;&#x2122;s wireless connections. A longer interval (5000-9999 seconds) relaxes security on wireless connections. The reauthentication period setting does not affect a wireless connectionâ&#x20AC;&#x2122;s throughput. The engaged Access Port continues to forward traffic during the reauthentication process.

Wireless Configuration 5-11

10.In the Max. Retries field, set the maximum number of retries for a client to successfully reauthenticate after failing to complete the EAP process. If the mobile unit fails the authentication process in specified number of retries, the switch will terminate the connection to the mobile unit.

Advanced Settings 11.The MU Quiet Period field allows the administrator to specify the idle time (in seconds) between a mobile unit’s authentication attempts, as required by the server. 12.The MU Timeout field allows the administrator to specify the time (in seconds) for the mobile unit’s retransmission of EAP-Request packets. 13.The MU Tx Period field allows the administrator to specify the time period (in seconds) for the server’s retransmission of the EAP-Request/Identity frame. 14.The MU Max Retries field allows the administrator to set the maximum number of times for the mobile unit to retransmit an EAP-Request frame to the server before it times out the authentication session. Note that this is a different value from the Max Retry field at the top of the window. 15.The Server Timeout field indicates the maximum time (in seconds) that the switch will wait for the server’s transmission of EAP Transmit packets. 16.The Server Max Retries field allows the administrator to set the maximum number of times for the server to retransmit an EAP-Request frame to the client before it times out the authentication session. Note that this is a different value from the Max. Retries field at the top of the window.

RADIUS Client Accounting and Syslog Setup 17.Use the Enable Accounting check box to enable saving the RADIUS logs on the device’s Compact Flash (CF) card. 18.If accounting is enabled, enter the maximum amount of time a client will wait for an acknowledgement from the RADIUS accounting server before resending the accounting packet in the MU Timeout field. In the Retries field, enter the maximum number of times for the client will resend the accounting packet to the RADIUS accounting server before giving up. 19.To enable 802.1x EAP message logging to an external Syslog server, check the Enable Syslog box and then specify the IP address of the syslog server in the Syslog Server IP field. 20.Click the Ok button to save changes.

5.3.3 Configuring Kerberos Authentication Kerberos provides a strong authentication method for client/server applications by using secret-key cryptography. Using this protocol, a client can prove their identity to a server (and vice versa) across an insecure network connection. After a client and server use Kerberos to prove their identity, they can encrypt all communications to assure privacy and data integrity. 1. Select the Kerberos radio button to enable Kerberos authentication. 2. Click the Kerberos Configuration button to display a sub-screen for authentication settings.

5-12 WS2000 Wireless Switch System Reference Guide

3. A realm name functions similar to a DNS domain name. In theory, the realm name is arbitrary; however, in practice, a Kerberos realm is typically named using an uppercase version of the DNS domain name that is associated with hosts in the realm. Specify a realm name that is case-sensitive, for example, MyCompany.com. 4. Specify a Username for the Kerberos configuration. 5. Specify a Password for the Kerberos configuration. The Key Distribution Center (KDC) implements an authentication service and a ticket granting service, whereby an authorized user is granted a ticket that is encrypted with the userâ&#x20AC;&#x2122;s password. The KDC has a copy of every user password. 6. Specify a server IP address and a port to be used as the Primary KDC. 7. Optionally, specify a Backup KDC server by providing the IP address and port. 8. Optionally, specify a Remote KDC server by providing the IP address and port. 9. Make sure that NTP is enabled (go to [System Configuration] --> NTP Servers from the left menu). NTP is required for Kerberos Authentication. For more information, see Specifying a Network Time Protocol (NTP) Server. 10.Click Ok when done.

5.3.4 Setting the Encryption Method Encryption applies a specific algorithm to data to alter its appearance and prevent unauthorized reading. Decryption applies the algorithm in reverse to restore the data to its original form. Sender and receiver employ the same encryption/decryption method. The WS 2000 Wireless Switch provides four methods for data encryption: WEP, KeyGuard, WPA-TKIP, and WPA2-CCMP (802.11i). The WPA-TKIP and KeyGuard methods use WEP 104-bit key encryption. WPA-TKIP offers the highest level of security among the encryption methods available with the switch. The available encryption methods also depend on the authentication method used. Kerberos authentication supports only the WEP 128 (104 bit key) and KeyGuard encryption methods.

5.3.5 Configuring WEP Encryption Wired Equivalent Privacy (WEP) is a security protocol specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11b. WEP is designed to provide a WLAN with a level of security and privacy comparable to that of a wired LAN. WEP might be all that a small-business user needs for the simple encryption of wireless data. However, networks that require more security are at risk from a WEP flaw. The existing 802.11 standard alone offers administrators no effective method to update keys. Key changes require the manual reconfiguration of each Access Port. An unauthorized person with a sniffing tool can monitor a network for less than a day and decode its encrypted messages.

Wireless Configuration 5-13

WEP is available in two encryption modes: 40 bit (also called 64-bit) and 104 bit (also called 128 bit). The 104-bit encryption mode provides a longer algorithm that takes longer to decode than that of the 40-bit encryption mode. NOTE: The WEP 128 encryption mode allows devices using 104-bit key and devices using 40-bit keys to talk to each other using 40-bit keys, if the 104-bit devices permit this option. 1. Choose between the WEP 64 (40-bit key) and WEP 128 (104-bit key) option by selecting the appropriate radio button. 2. To use WEP encryption with the No Authentication selection, click the WEP Key Settings button to display a sub-screen for entering keys.

3. When finished, click the Ok button to close this screen. 4. Specify a Pass Key and click the Generate button. The pass key can be any alphanumeric string. The switch, other proprietary routers, and Motorola cards in mobile units (MUs) use an algorithm to convert an ASCII string to the same hexadecimal number, but this conversion is not required for a wireless connection. 5. Use the Key #1-4 fields to specify key numbers that use 26 hexadecimal characters. Select one of these keys for active use by selecting its radio button. Four different keys can be specified, allowing each WLAN to have a different key. 6. Click the Apply button on the WLAN Security screen to save changes.

5.3.6 Configuring WPA/WPA2-TKIP Encryption Wi-Fi Protected Access (WPA) is specified in the IEEE Wireless Fidelity (Wi-Fi) standard, 802.11i. This security standard provides more sophisticated data encryption than WEP. WPA is designed for corporate networks and small-business environments where more wireless traffic allows quicker discovery of encryption keys by an unauthorized person. WPAâ&#x20AC;&#x2122;s encryption method is Temporal Key Integrity Protocol (TKIP). TKIP addresses WEP weaknesses with a re-keying mechanism, a per-packet mixing function, a message integrity check, and an extended initialization vector. WPA/WPA2 also provides strong user authentication that is based on 802.1x EAP. 1. Select the WPA/WPA2-TKIP radio button to enable Wi-Fi Protected Access (WPA) with Temporal Key Integrity Protocol (TKIP).

5-14 WS2000 Wireless Switch System Reference Guide

2. To use WPA/WPA2-TKIP encryption with 802.1x EAP authentication or the No Authentication selection, click the WPA/WPA2-TKIP Settings button to display a sub-screen for key and key rotation settings.

3. To Enable WPA2 check the Use WPA2 check box to use WPA2 encryption in conjunction with WPA-TKIP. 4. If using WPA2 in conjunction with 802.1x EAP authentication you may enable Pre-Authentication and Opportunistic Key Caching by checking the corresponding check boxes. 5. Check the Broadcast Key Rotation check box to enable or disable the broadcasting of encryption-key changes to mobile units. 6. Specify a time period in seconds for broadcasting encryption-key changes to mobile units. Set key broadcasts to a shorter time interval (at least 300 seconds) for tighter security on this WLANâ&#x20AC;&#x2122;s wireless connections. Set key broadcasts to a longer time interval (at most, 80,000 seconds) to relax security on wireless connections. A Pre-Shared Key (PSK) is an Internet Protocol security (IPSec) technology that uses a shared, secret key for authentication in IPSec policy. IPSec is a set of industry-standard, cryptography-based protection services and protocols. IPSec protects all protocols in the TCP/IP protocol suite and Internet communications by using Layer Two Tunneling Protocol (L2TP). Use pre-shared key authentication only in a WLAN environment intended for relaxed security. The administrator can specify the key either as an ASCII passphrase or as a 128-bit key. All WLAN clients must use the same PSK. 7. Select either the ASCII Passphrase or 256-bit Key radio button. 8. If ASCII Passphrase is selected, specify a 8 to 63 character alphanumeric string. The alphanumeric string allows character spaces. The switch converts the string to a numeric value. 9. To use the 256-bit Key option, enter 16 hexadecimal characters into each of the four fields. 10.Click the Ok button to return to the WLAN security screen. 11.Click the Apply button on the WLAN Security screen to save changes.

5.3.7 Configuring WPA2-CCMP (802.11i) Encryption WPA2 is a newer 802.11i standard that provides stronger wireless security than WiFi Protected Access (WPA) and WEP. CCMP is the security protocol used by AES. It is the equivalent of TKIP in WPA. CCMP computes a Message Integrity Check (MIC) using the well known, and proven, Cipher Block Chaining Message Authentication Code

Wireless Configuration 5-15

(CBC-MAC) method. Changing even one bit in a message produces a totally different result thus providing strong authentication. WPA2-CCMP is based upon the concept of a Robust Security Network (RSN), which defines a hierarchy of keys that have a limited lifetime, similar to TKIP. Also like TKIP, the keys that the administrator provides are used to derive other keys. Messages are encrypted using a 128-bit secret key and a 128-bit block of data. The end result is encryption that is extremely secure. 1. Select the WPA2-CCMP radio button to enable Wi-Fi Protected Access (WPA) with Temporal Key Integrity Protocol (TKIP). 2. To use WPA-TKIP encryption with 802.1x EAP authentication or the No Authentication selection, click the WPA-TKIP Settings button to display a sub-screen for key and key rotation settings.

3. Check the Broadcast Key Rotation check box to enable or disable the broadcasting of encryption-key changes to mobile units. 4. Specify a time period in seconds for broadcasting encryption-key changes to mobile units. Set key broadcasts to a shorter time interval (at least 300 seconds) for tighter security on this WLANâ&#x20AC;&#x2122;s wireless connections. Set key broadcasts to a longer time interval (at most, 200,000 seconds) to relax security on wireless connections. 5. Select either the ASCII Passphrase or the 256-bit Key radio button. 6. If ASCII Passphrase is selected, specify a 8 to 63 character ASCII string. The ASCII string allows character spaces. The switch converts the string to a numeric value. 7. To use the 256-bit Key option, enter 16 hexadecimal characters into each of four fields. 8. WPA2-CCMP Mixed Mode enables WPA2-CCMP and WPA-TKIP Clients to operate simultaneously on the network. Enabling this option allows backwards compatibility for clients that support WPA-TKIP but do not support WPA2-CCMP. 9. The Fast Roaming area provides two fields. Enabling Pre-Authentication enables a client associated with one Access Port to carry out an 802.1x authentication with another Access Port before it roams over to it. The WS2000 switch will cache the keying information of the client until it roams to the new Access Port. This enables the roaming the client to start sending and receiving data sooner by not having to do 802.1x authentication after it roams. Enabling Opportunistic Key Caching allows the switch to use a Pairwise Master Key (PMK) derived with a client on one Access Port with the same client when it roams over to another Access Port. Upon roaming the client does not have to do 802.1x authentication and can start sending/receiving data sooner.

The list employs an adoption rule for allowing or denying specific mobile units by way of exception. 1. Select Allow or Deny from the pull-down menu. This rule applies to all mobile units except those listed in the table. If Allow is visible, the access criteria (MAC addresses) will be used to indicated which mobile units will be allowed access to the Access Port. If Deny is visible, the access criteria will be used to indicated which mobile units should not be allowed access. 2. Click the Add button to add a new entry to the list.

5-18 WS2000 Wireless Switch System Reference Guide

3. Each entry in the table specifies one or more MAC address to be used to match with a mobile unit’s MAC address that is attempting to gain access to the WLAN. Specify a single address (by specifying Start Address only) or a range of MAC access (by using both the Start Address and the End Address). For example, if Allow is selected, all mobile units that match any of the specified MAC addresses or MAC address ranges in the table can be adopted by the WLAN. If Deny is selected, all mobile units that match any of the specified MAC addresses or MAC address ranges in the table cannot be adopted by the WLAN. 4. Click the Apply button to save changes.

5.4 Configuring Access Ports The WS 2000 Wireless Switch automatically detects Access Ports when they are attached to one of the switch’s LAN ports. When the switch starts communication with an Access Port that can be adopted by the switch, it uploads the firmware appropriate for the Access Port. At this time, the Access Port becomes active. The switch also automatically adds the Access Port to the list of known ports under the left menu item, [Network Configuration] --> Wireless --> APs/Radios --> <Access Port Name>.

For an Access Port to be adopted by the WS 2000 Wireless Switch, three things must be configured: 1. The Country field in the System Settings screen must be set. 2. The Access Port’s MAC Address must be set as one of the addresses that can be adopted by one of the enabled WLANs. 3. A WLAN that can adopt Access Port must be associated with an enabled subnet. (See Configuring Wireless LANs.) The switch can adopt up to six Access Ports at a time, but the number of Access Ports listed can exceed six in number. A dual-radio 802.11a/b Access Port counts as one Access Port with respect to the maximum allowed; however, each radio will be listed as a separate Access Port in the list of Access Ports.

Wireless Configuration 5-19

The switch creates a default name for a newly found switch consisting of “AP” and a unique number. During this detection process, the switch collects the following information from the Access Port: MAC address

Each Access Port has a unique Media Access Control (MAC) address by which it is identified. This address is burned into the ROM of the Access Port. Also, this address appears on a sticker attached to the bottom of the Access Port.

Serial Number

Each Access Port has a unique serial number printed on the device at the time of manufacturing. This address is burned into the ROM of the Access Port.

AP Type

This field lists the model number of the Access Port (i.e. AP100, AP300)

Radio type

This field indicates the wireless protocol that the Access Port follows. The WS 2000 Wireless Switch supports 802.11b and 802.11 a/b dual-radio Access Ports.

Adopted by

This field contains a list of defined WLANs that have adopted this Access Port (see Configuring Wireless LANs and Access Port Radio Adoption List for the process of adopting an Access Port).

The switch also sets several default values for the channel and the power level based upon the Location information set in the System Settings screen and upon settings in the Access Port Default Settings screen for the radio type. The WS 2000 Wireless Switch GUI also allows the administrator to refine the basic Access Port configuration that is set at the point of detection. To examine or change that information: 1. Select [Network Configuration] --> Wireless --> Access Ports from the left menu and then click the + to the left of the menu item. The detected Access Ports will be listed under the menu item, with the radio type listed in brackets (for example, [B]). 2. Select the Access Port item to examine or modify. There are two ways to distinguish between Access Ports when they are labeled with the default “AP#” name. • Look on the bottom of the Access Ports and take note of the MAC address (which looks like AA:BB:CC:DD EE:FF) and compare it with the MAC address in the Access Port windows. • Note the order in which Access Ports were plugged into the switch. The Access Port numbers are assigned in order, starting with AP1. When an Access Port has multiple radios, each radio is assigned an AP number.

5-20 WS2000 Wireless Switch System Reference Guide

The following screen is displayed with the settings for the selected Access Port.

3. From this screen, the administrator can change several pieces of information about each Access Port. Name

Administrators can change the names of the Access Ports from Access Port# to something much more descriptive, so that they can easily identify which Access Port is being referenced in the various screens and in the left menu. The name is limited to a string of 13 characters.

Location

This field is a memory aid for the administrator. Enter text that describes where the Access Port is physically located. The name is limited to a string of 13 characters.

Asset Name

This field is also a memory aid for keeping track of the organizational asset; Enter any value that uniquely identifies this asset.

Adopt this Access Port

This button opens a dialogue box which allows you to adopt an Access Port into one or more WLANs.

4. In the Radio Settings area, the administrator can specify a number of characteristics of the radio. Placement

Select either Indoors or Outdoors from the Placement pop-up menu. The setting will affect the selection available for several of the other advanced settings.

Channel

Specify a channel for communications between the Access Port and mobile units. The range of legally approved communications channels varies depending on the installation location. It is best to use a different channel number for each Access Port. Communications will be the clearest for nearby Access Ports if the channel numbers are 5 numbers apart (1, 6, 11).

Power Level Specify a Power Level in milliwatts (mW) for RF signal strength. The optimal power level is best determined by a site survey prior to installation. Available settings include 1, 5, 15, 30, and 100. Consult the site survey for recommendations of the power level. Set a higher power level to ensure RF coverage in WLAN environments that have more electromagnetic interference or greater distances between the Access Port and mobile units. Decrease the power level according to the proximity of other Access Ports. Overlapping RF coverage may cause lost packets and difficulty for roaming mobile units trying to engage an Access Port.

Wireless Configuration 5-21

MU dB This is a Motorola specific feature. This value indicates the amount of power in dBm that the MU Power Level should reduce its Tx power by with respect to the Tx power of the AP. This feature is used to reduce Adjustment the amount of radio noise in the environment for better reception.

To comply with Dynamic Frequency Selection (DFS) requirements in the European Union, the 802.11a radio on AP300 Access Ports will come up on a random channel each time it is powered on. NOTE: With this mode, channel can not be manually selected.

Automatic Mode (Automatic Channel Selection) Select this radio button to enable Automatic Channel Selection (ACS) feature of WS2000/ AP300. With this mode, the AP will scan the available channels and select the one in which least number of beacons is heard. NOTE: With this mode, channel can not be manually selected.

Placement

Select either Indoors or Outdoors from the Placement pop-up menu. This setting will affect the power levels and channels available for selection.

Channel

Select a channel number from the Channel drop-down menu on which the Access Port should communicate with associated MUs. NOTE: The available channels vary depending on the location setting of the switch.

Power Level

Select a power level from the Power Level drop-down menu that will be used for radio communications between the Access Port and the MUs. Set a higher power level to ensure RF coverage in WLAN environments that have more electromagnetic interference or greater distances between the Access Port and mobile units (MUs). Decrease the power level according to the proximity of other Access Ports. Overlapping RF coverage may cause lost packets and difficulty for roaming MUs trying to engage an Access Port.

Wireless Configuration 5-23

Antenna Diversity

Use the drop-down menu to configure the Antenna Diversity settings for Access Ports that use external antennas. Full Diversity: Utilizes both antennas to provide antenna diversity Primary Only: Enables only the primary antenna Secondary Only: Enables only the secondary antenna

NOTE: Antenna Diversity should only be enabled if the Access Port has two matching external antennas. RTS Threshold

Set the Request to Send Threshold (RTS Threshold) by specifying a number. RTS is a transmitting station’s signal that requests a Clear To Send (CTS) response from a receiving station. This RTS/CTS procedure clears the air when many mobile units (MUs) are contending for transmission time. Modifying this value allows the administrator to control the number of data collisions and thereby enhance communication with nodes that are hard to find because of other active nodes in the transmission path. In this field, the administrator can specify a Request To Send (RTS) threshold (in bytes) for use by the WLAN’s adopted Access Ports. This setting initiates an RTS/CTS exchange for data frames that are larger than the threshold, and sends (without RTS/CTS) any data frames that are smaller than the threshold. Consider the tradeoffs when setting an appropriate RTS threshold for the WLAN’s Access Ports. A lower RTS threshold causes more frequent RTS/CTS exchanges. This consumes more bandwidth because of the additional latency (RTS/CTS exchanges) before transmissions can commence. A disadvantage is the reduction in data-frame throughput. An advantage is quicker system recovery from electromagnetic interference and data collisions. Environments with more wireless traffic and contention for transmission make the best use of a lower RTS threshold. A higher RTS threshold minimizes RTS/CTS exchanges, consuming less bandwidth for data transmissions. A disadvantage is less help to nodes that encounter interference and collisions. An advantage is faster data-frame throughput. Environments with less wireless traffic and contention for transmission make the best use of a higher RTS threshold.

Set Rates

Click the Set Rates button to open a subscreen where the default Basic Rates and Supported Rates for 802.11b/g Access Ports can be set. A list of available Basic and Supported rates for the radio are listed in two columns with check boxes next to each rate. Selecting a rate as a Basic Rate automatically selects that rate as a Supported Rate and disables the option in the Supported Rates column.

5-24 WS2000 Wireless Switch System Reference Guide

Beacon Settings

Set the Access Port beacon settings by clicking on the Beacon Settings button. Set the following beacon values. Beacon Interval—A beacon is a packet broadcast by the adopted Access Ports to keep the network synchronized. Included in a beacon is information such as the WLAN service area, the access-port address, the broadcast destination addresses, a time stamp, and indicators about traffic and delivery such as a DTIM. Specify a beacon interval in units of 1,000 microseconds (K-us). This is a multiple of the DTIM value, for example, 100 : 10. Increase the DTIM/beacon settings, lengthening the time, to let nodes sleep longer and preserve their battery life. Decreasing this value (shorten the time) to support streaming-multicast audio and video applications that are jitter-sensitive. DTIM Period—A DTIM is periodically included in the beacon frame that is transmitted from adopted Access Ports. The DTIM period determines how often the beacon contains a DTIM, for example, 1 DTIM for every 10 beacons. The DTIM indicates that broadcast and multicast frames, buffered at the Access Port, are soon to arrive. These are simple data frames that require no acknowledgment, so nodes sometimes miss them. In this field, the administrator can specify a period for the Delivery Traffic Indication Message (DTIM). This is a divisor of the beacon interval (in milliseconds); for example, 10 : 100. Increase the DTIM/beacon settings, lengthening the time, to let nodes sleep longer and preserve their battery life. Decrease this settings (shortening the time) to support streaming-multicast audio and video applications that are jitter-sensitive. Primary WLAN—Select the primary WLAN when the 802.11a broadcast protocol is used. When a WLAN is associated with a 801.11a broadcaster, only one ESSID can be broadcast from the Access Port (even though three are supported by the switch). This field specifies which ESSID to broadcast. Security Beacon—Check the Security Beacon box if the WLAN associated with the Access Port needs to be secure. If this feature is selected, the WLAN will not broadcast the ESSID. This selection eliminates the possibility of hackers tapping in to the WLAN without authorization by “stealing” the ESSID.

5.5.2 Radio-Specific Settings The fields below are only available for some radio types, as indicated in the second column. Check this check box to enable the Uniform Spreading feature of the AP300.

Support Short Preamble

Check the Support Short Preamble box to allow the Access Port to communicate with the MUs using a short 56-bit preamble. A preamble is the beginning part of a frame. The preamble comprises such elements as robust carrier sensing, collision detection, equalizer training, timing recovery, and gain adjustment. The administration can choose between a long or short preamble for dataframe transmission from the WLANâ&#x20AC;&#x2122;s adopted Access Ports.

b/g

Use the long preamble setting (the default) for legacy wireless equipment that is not capable of dealing with short preambles. Use the short preamble setting where legacy equipment is not an issue and maximum throughput is desired, for example when streaming video or Voice-over-IP applications are used. Use this menu to set radio rates on the Access Port to one of the following settings:

802.11 b/g mode

B and G: Clients that support 802.11b and/or 802.11g rates may associate with the Access Port. G only: Only clients that support 802.11g rates may associate with the Access Port. b/g

5.7 Quality of Service Configuration Disruptions in service in a wireless environment can be a significant issue in environments that have high bandwidth demands (for example, when VoIP and video broadcasts are commonplace). Wireless Internet users can also suffer disruptions due to environmental conditions, such as adverse transmission situations or a large number of wireless devices that affect radio frequency communications. The WS 2000 Wireless Switch allows an administrator to adjust several parameters that can improve the quality of service (QoS) to wireless users. Select Wireless --> Wireless QoS from the navigation menu on the left to specify how the bandwidth can be shared, how to distribute the bandwidth among the WLANs that are in service, or how to prioritize voice and multicast communications.

5-30 WS2000 Wireless Switch System Reference Guide

5.7.1 Setting the Bandwidth Share Mode First, specify how the networking resources will be shared. The Bandwidth Share Mode provides three allocation options: Off

Packets are served on a first-come-first-served basis. If this option is selected, the information in the Bandwidth Share for Each WLAN area is ignored.

Round Robin

Bandwidth is equally shared among all active WLANs. If this option is selected, the Weight (%) in the Bandwidth Share for Each WLAN area is automatically set to be the same for all active WLANs, and the values are not editable.

Weighted Round Robin

The bandwidth can be configured on a per WLAN basis. If Weighted Round Robin is the selected Bandwidth Share Mode, the weight for each WLAN can be set either using the Weight field or the Weight (%) field. When one is set, the application automatically adjusts the other field. Only the information for active WLANs can be edited.

Rate Limiting

The bandwidth can be configured to a maximum threshold value in Kilobytes per Second (kbps).

Wireless Configuration 5-31

Bandwidth Share for Each WLAN Table The fields in this table are: WLAN Name

This field lists the WLANs on the switch by name (the same name that you see in the left menu). You cannot change the name of the WLAN in this field. Go to the Wireless screen to change a WLAN name.

Weight

The Weight field specifies the relative amount of bandwidth provided to the given WLAN as compared to the other WLANs. For example, if WLAN1 has Weight set to 3 and WLAN2 has Weight set to 1, WLAN1 will get 3 times as much bandwidth as WLAN2. When the Weight field is changed, the weight percentage adjusts automatically to match.

Weight (%)

This field is automatically calculated and cannot be edited. This field specifies the percentage of bandwidth allocated for each of the WLANs. If the Bandwidth Share Mode is set to Round Robin, the Weight (%) will be the same for all active WLANs. If the Bandwidth Share Mode is set to Weighted Round Robin, the value is calculated based upon the Weights set for each of the WLANs. For example, if WLAN1 has Weight set to 3 and WLAN2 has Weight set to 1, the application will automatically set the weight percentage to 75% for WLAN1 and 25% for WLAN2.

5.7.2 Configuring Voice Prioritization and Multicast Address Settings To ensure better performance with Voice over IP (VoIP) broadcasts, the administrator can enable voice prioritization for particular multicast addresses within a WLAN. In the table, specify the multicast addresses by filling out the fields: WLAN Name

This field lists the WLANs on the switch by name (the same name that you see in the left menu). You cannot change the name of the WLAN in this field. Go to the Wireless screen to change a WLAN name.

Use Voice Prioritization

Check this box to enable prioritization of voice over data for RF transmissions for the associated WLAN. This setting reduces the latency that might occur when data transmissions and VoIP transmissions compete for the same resources. Latency is usually experienced as broken or delayed speech or sound.

Multicast Address #1 and Multicast Address #2

Use the two Multicast Address fields to specify one or two MAC addresses to be used for multicast applications. Some VoIP devices make use of multicast addresses. Using this mechanism ensures that the multicast packets for these devices are not delayed by the packet queue.

NOTE: Voice prioritization and multicast addressing will only affect active WLANs. Applying these settings to a inactive WLAN will have no effect. To make a WLAN active, go to the Wireless screen.

5.8 Setting Up Port Authentication for AP300 Access Ports 802.1x port authentication is used to provide security and authentication for all wired clients on a WLAN. The WS 2000 Wireless Switch supports 802.1x port authentication for the AP300 Access Ports connected to it. It uses a username and password for all ports that can be configured from the wireless switch. Select [Network Configuration] --> [Access Ports] --> 802.1x Port Authentication from the navigation menu on the left.

5-32 WS2000 Wireless Switch System Reference Guide

To set up Port Authentication for all adopted AP300 Access Ports: 1. In the Username field, specify a 802.1x username for all AP300 Access Ports adopted by the switch. To use the default username click the <- Default button next to the Username field. 2. In the Password field, specify a 802.1x password for all AP300 Access Ports adopted by the switch. To use the default password click the <- Default button next to the Password field. 3. Click the Set on all adopted AP300 button to set the username and password specified in the Username and Password fields on all AP300 Access Ports adopted by the switch.

5.9 Rogue Access Point (Port) Detection Rogue Access Points (APs) are a hot area of concern with respect to LAN security. “Rogue AP” is a term used to describe an unauthorized access point that is connected to the production network or operating in a standalone mode (in a parking lot or in a neighbor’s building). Rogue APs, by definition, are not under the management of network administrators and do not conform to any network security policies. Although 802.1x security settings should completely protect the LAN, organizations are not always fully compliant with the newest wireless-security best practices. In addition, organizations want to be able to detect and disarm rogue APs. The WS 2000 Wireless Switch provides a mechanism for detecting and reporting rogue APs. Select [Network Configuration] --> Wireless --> Rogue AP Detection from the navigation menu on the left.

Wireless Configuration 5-33

The Rogue AP Detection screen allows the administrator to determine how thoroughly the switch will search for rogue APs as well as list the approved APs.

5.9.1 Setting Up the Detection Method The WS 2000 Wireless Switch provides three methods for detecting rogue Access Points (APs). Use the top part of the Rogue AP Detection screen to set the method or methods that the switch will use to detect rogue APs. 1. Check the RF Scan by MU box if you want the switch to work with mobile units (MUs) to detect a rogue AP. With this option selected, each MU reports whether it supports rogue AP detection mechanisms. If so, the switch sends WNMP requests, at regular intervals, to the MU to get a list of APs. The MU scans all the channels for APs in the vicinity. The MU then prepares a list of APs (BSSIDs) and sends it back to the switch using WNMP response message. The switch processes this information. 2. Check the RF Scan by AP box if you want the switch to work with the APs to detect a rogue AP. By default, this method is selected. With this option enabled, the switch sends a WISP configuration message to each adopted AP that indicates that rogue AP detection is needed. Each AP listens for beacons in its present channel and passes the beacons to the switch without modification. The switch then processes the beacons to determine whether any of them are rogues. This method is less disruptive than the RF Scan by MU mode. 3. Check the RF Scan by Detector AP box if you have set up a detector AP on the LAN and want the switch to work with that AP to detect rogue APs. To set an AP as a detector AP, go to the screen for the adopted AP under APs/Radios in the navigation menu and check the appropriate box. 4. Check the RF Scan by Full Detector AP box if you have set up an AP on the LAN that acts exclusively as a Detector AP and want the switch to work with this AP to detect rogue APs. To set an AP to act as a full detector AP, go to the screen for that adopted AP under APs/Radios in the navigation menu and check the appropriate box. When an AP is set up as a Full Detector AP then it will not serve any data clients.

5-34 WS2000 Wireless Switch System Reference Guide

NOTE: Note that only some access ports have the capability of being a Detector AP, including Motorola AP 100, AP 200, and AP 300 Access Ports. 5. In the Scan Interval field, enter a time interval (in minutes) between detection RF scans. Do this for each of the selected detection methods. By default, these scans are set at one hour intervals. NOTE: Scan interval for Full Detector AP is defined in seconds. For other scans, the interval is defined in minutes.

5.9.2 Defining and Maintaining Approved AP List Rules The lower half of the Rogue AP Detection screen specifies rules that determine whether a detected AP can be approved or not. Each entry in the table works as an AP evaluation rule. You can specify a particular MAC address or a particular ESSID, or you can indicate that any MAC address or ESSID will work. However, if you select Any MAC and Any ESSID on the same line, all APs will be approved. Up to 20 rules can be defined. 1. Check the Approve Any AP Having a Symbol Defined MAC Address box to indicate that any Motorola AP (that is, one that has a known Motorola MAC address) is an approved AP. 2. Click the Add button to add a line in the rule table and then fill out the following table cells: Any MAC

5.9.4 Setting SNMP Traps for Rogue APs It is also possible to set a trap for a rogue AP. 1. Go to [System Configuration] --> SNMP Access --> SNMP Traps from the navigation menu.

Wireless Configuration 5-39

2. Check the Rogue AP box (in the lower right area of the screen) to generate a trap when a rogue (unauthorized) access port (AP) is detected. The detection process is non-disruptive and will not affect the performance of the switch. The detection functionality is greatly enhanced when the Approved AP list is filled out on the AP List screen under Rogue AP Detection.

5.10 Configuring Wireless Intrusion Protection System (WIPS) The Wireless Intrusion Protection System (WIPS) provides additional wireless LAN security by monitoring the airwaves for any kind of Denial of Service (DoS) attacks. It is also able to actively suppress any rogue clients and APs in the network. Motorolaâ&#x20AC;&#x2122;s WIPS solution utilizes AP300s that act as dedicated sensors and send out relevant information to a centralized WIPS server. The WIPS server correlates all the data and provides threat mitigation services. Go to [Network Configuration]--> Wireless --> WIPS from the navigation menu.

1. Click the Enable WIPS check box in the WIPS mode section. 2. Check the box next to each of the APs or Sensors which you wish to convert to a dedicated detector port. 3. Once all desired APs have been checked, click the Convert button to begin the conversion process. NOTE: If no APs or Sensors are displayed in the tables, go to the properties page for each AP you wish to use as a WIPS detector and select the Dedicate this AP as a Detector AP option and return the WIPS screen. 4. Click the Apply button to save any changes made on this screen. Navigating away from the current screen without clicking the Apply button results in all changes to this screen being lost.

5.11 Wireless Intrusion Detection System The Motorola Wireless Intrusion Detection System (WIDS) protects against a wide range of malicious attacks on the WS2000 Wireless Switch. This feature inspects each packet that is received by the WS2000 and then based on analysis decides if an intrusion is happening on the device. By default, WIDS is disabled. It can be enabled from the [Network Configuration]-->Wireless-->WIDS screen.

For WIDS, a violation is when excessive numbers of packets of the same type are received. WIDS keeps track of each packet type that is received and when a threshold value is crossed, raises a violation alarm. Appropriate action can be performed based on the alerts. WIDS provides alerts when thresholds are crossed for: • MUs • Radio • Switch WIDS keeps tracks of these violations: • probe-req - Probe Requests • auth-assoc-req - Authentication Association Requests • deauth-deassoc-req - Deauthentication De-association Requests • auth-fails - Authentication Failures • crypto-replay-fails - Cryptography Replays Failures • 802.11-replay-fails - 802.11x Replays Failures • decrypt-fails - Decryption Failures • unassoc-frames - Unassociated Frames • eap-starts - EAP Start Frames

5-42 WS2000 Wireless Switch System Reference Guide

WIDS also keep track of anomalies. An anomaly is defined as an event which is different from the general occurrences on a WS2000. The following anomalies are tracked: • null-dst - NULL destination • same-src-dst - Same source and destination address • mcast-src - Source MAC is multicast • weak-wep-iv - Weak WEP • tkip-cntr-meas - TKIP counter measures • invalid-frame-len - Invalid frame length

5.11.1 WIDS Configuration The WIDS parameters for violations and anomalies can be configured from the Configuration tab of the WIDS screen. The tab is enabled when the Enable WIDS check box is selected. To configure WIDS: 1. Enter a time value in seconds for the Detect Window. WIPS checks for violations and anomalies every detect window value. For example, if the value is 30 seconds, WIPS checks for violations and anomalies every 30 seconds.

5.11.1.1 Excessive Violation Parameters Use the Excessive Violation Parameters section to set violation parameters. Violation parameters threshold values can be set for MUs, Radio, and Switch. To set the Excessive Violation Parameter value: 1. Click on the violation that you want to monitor. 2. If you would like to monitor the MU for a violation, click under the MU Threshold column for that violation. The column becomes editable. Enter a suitable value for the threshold. You can similarly set the thresholds for the Radio and the Switch for the violation. 3. Use the Time to Filter column to set the time duration during which any packets received from the MU will be filtered out. For example, if this value is set to 135 seconds, the MU is filtered out for 135 seconds. The Radio Threshold and Switch Threshold columns enables you to set up threshold values upon reaching which a SNMP trap is generated.

5.11.1.2 Anomaly Violation Parameters Use the Anomaly Violation Parameters section to set the parameters for Anomalies. When enabled, the MU is filtered out for the duration specified in the Time to Filter column. 1. Enable or disable Anomaly Violation detection by selecting the MU Threshold check box. 2. Use the Time to Filter column to set the time duration during which any packets received from the MU will be filtered out. For example, if this value is set to 135 seconds, the MU is filtered out for 135 seconds. 3. Click the Apply button to save any changes made on this screen. Navigating away from the current screen without clicking the Apply button results in all changes to this screen being lost.

Wireless Configuration 5-43

5.11.2 Filtered MUs The Filtered MUs screen displays a list of all MUs that have been filtered out by WIDS. You can, if required, remove any or all MUs listed in the Filtered MUs table. The Filtered MUs table displays the following: MU MAC

The MAC address of the MU that has been filtered out.

Radio

The Radio that has been filtered out

Violation Type

The violation that caused the MU to be filtered out

Time Left

The duration after which the MU will not be filtered out.

Use the check box to the left of each filtered MU to select it for removing it from the Filtered MUs table. Use the Delete MU Entry button to remove the selected MU or MUs. You can also remove all the MUs in the table by clicking the Delete All MU Entries button. To refresh the Filtered MUs table, click the Refresh Table button.

5-44 WS2000 Wireless Switch System Reference Guide

5.12 Smart Scan Each radio, depending on the country of operation, provides a large number of channels for data transmission. This means that when a MU roams from one AP to another, it has to scan all available channels for that radio to find the WLAN it was connected to. This scan process takes time depending on the number of channels to scan. When deploying real-time applications such as VoIP or video-streaming over wireless, this roaming latency creates a break in these application. Smart Scan allows you to select the channels to scan on a radio to reduce this latency. To select the channels to scan, navigate to [Network Configuration]-->Wireless-->APs/Radios->smartscan. The smartscan screen displays.

To select the channels to scan: 1. Select the channels to scan for each radio type. Multiple channels can be selected by using the [CTRL Key] + mouse click combination. 2. Click Add button to move the selected channels from the Channel Available list to the Channel. Assigned list. Scan will be performed only on the channels in the Channel Assigned list. Select channels and click Delete button to remove those channels from the Channel Assigned list and move them to the Channel Available list. The removed channels will not be scanned. You can select the scan channels for both radio types.

Wireless Configuration 5-45

5.13 Self Heal A self-healing network is one that is capable of maintaining the availability of the network under all circumstances. The network can self-manage in response to the events that occur within the network. Self heal for WS2000 is provided by the device maintaining a Neighbor Table with entries for each device in its neighborhood. Self heal can be activated from [Network Configuration]-->Wireless-->APs/Radios-->selfheal menu item.

Self healing consists of two different features, Neighbor Recovery and Interference Avoidance. Neighbor Recovery uses a Neighbor Table to keep track of all its immediate neighbor portals. Interference Avoidance detects interference on the channel on which the portal is operating and shifts the portal’s channel to an unused channel in the channel list. Neighbor Recovery When enabled, a portal listens to beacons of its neighbors configured in the Neighbor Table. The AP goes into monitoring mode once it has listened to a set number of beacons from its neighbor. After going into the monitoring mode, if the AP is not able to listen to the beacons from a neighbor, it considers that particular neighbor as being down and take appropriate neighbor recovery action as configured in the Neighbor Table. The following actions can be performed to recover the lost neighbor. • none - No action is taken to recover • raise-power - The AP raises its operating power to the maximum power level less the Offset value. • open-rates - The AP operates with its configured basic and supported rates. • both - Both the raise-power and open-rates actions are performed.

5-46 WS2000 Wireless Switch System Reference Guide

Interference Avoidance When enabled, the AP keeps track of the retry count for the Tx frames and if this count exceeds the threshold limit set in Average Retries field, triggers the Interference Avoidance feature. The AP then does a Automatic Channel Selection (ACS) and shifts its channel to one where there is no interference. The Hold Time specifies the time duration in seconds that the AP has to wait after having done a ACS before doing the next ACS.

5.14 Mesh Settings The WS2000 Wireless Switch provides support for creating and managing a mesh network. In a mesh network, there are more than two pathways of communication between each node. In a mesh network, each node communicates with the other nodes directly or by hops using other nodes as intermediary stops. As there are multiple paths between nodes, mesh networks provides reliability and offers redundancy. Mesh network is supported by the WS2000 Wireless Switch through APs that have mesh network support integrated in them. AP300 from Motorola is a thin AP that has in built support for Mesh networks. When a WS2000 is configured for Mesh support, it uses AP300s that have been adopted as base bridges or client bridges to establish mesh networks. To create and manage a Mesh Network, select [Network Configuration]-->Wireless-->APs/Radios-><Radio Name>. This radio must support Mesh network. The Radio Settings screen is displayed. Select the Mesh Settings tab on the screen to view the Mesh Settings screen.

A Mesh Base device is a device that allows other devices to connect to it as its client. The Mesh Base is also responsible to provide the redundancy and reliability. Each Mesh Base can support up to 6 Mesh Client devices. A Mesh Client is a device that connects to the Mesh Base to access the network resources.

Wireless Configuration 5-47

NOTE: A radio can act as a Mesh Base or as a Mesh Client or as both.

5.14.1 Mesh Base Setting Use the Mesh Base Settings area of the Mess Setting screen to set up the device as a Mesh Base device. To do so: 1.

6.2 Configuring User Authentication The WS 2000 Wireless Switch provides an integrated RADIUS server as well as the ability to work with external RADIUS and LDAP servers to provide user database information and user authentication. Several screens are available to configure the how the RADIUS server authentication works as well as set up the local user database and access policies. • The RADIUS Server screen allows the administrator to set the data source, the authentication type, and associate digital certificates with the authentication (see Configuring the RADIUS Server). • The LDAP screen allows the administrator to set up communication with an external LDAP server (see Configuring Lightweight Directory Access Protocol (LDAP) Authentication).

6-6 WS2000 Wireless Switch System Reference Guide

6.2.1 Configuring the RADIUS Server The WS 2000 Wireless Switch provides an integrated RADIUS server as well as the ability to work with external RADIUS and LDAP servers to provide user database information and authentication. The RADIUS Server page allows the admin to set up data sources, as well as specify authentication information for the built-in RADIUS server. Select [System Configuration] --> [User Authentication] --> RADIUS Server to set up the RADIUS server configuration.

1. Use the Data Source pull-down menu to select the data source for the local RADIUS server. • If Local is selected, the internal User Database will serve as the data source. Use the User Database screen to enter the user data. • If LDAP is selected, the switch will use the data in an LDAP server. Configure the LDAP server settings on the LDAP screen under RADIUS Server on the menu tree. • If LDAPS is selected, the switch will use the user data in a LDAP server and authenticate using client and CA certificates. Configure the LDAP server settings on the LDAP screen under RADIUS Server on the menu tree. 2. Use the TTLS/PEAP Configuration check boxes to specify the EAP types for the RADIUS server. TLS is selected by default and PEAP and TTLS are selectable options. • Protected EAP (PEAP) uses a TLS layer on top of EAP as a carrier for other EAP modules. PEAP is an ideal choice for networks using legacy EAP authentication methods. • Tunneled TLS EAP (EAP-TTLS) is similar to EAP-TLS, but the client authentication portion of the protocol is not performed until after a secure transport tunnel has been established. This allows EAPTTLS to protect legacy authentication methods used by some RADIUS servers. 3. If PEAP is selected, specify a Default Auth Type for PEAP to use from the pull-down menu. The options are GTC and MSCHAP-V2. • EAP Generic Token Card (GTC) is a challenge handshake authentication protocol that uses a

Administrator and User Access 6-7

hardware token card to provide the response string. • Microsoft CHAP (MSCHAP-V2) is an encrypted authentication method based on Microsoft's challenge/response authentication protocol. 4. If TTLS is selected, specify a Default Auth Type for TTLS to use from the pull-down menu. The options are MD5, PAP and MSCHAP-V2. • Message Digest 5 (MD5) is a secure hash function which converts a long data stream into a fixed size digest. It uses a 128-bit hash value to do the conversion. • Password Authentication Protocol (PAP) is a protocol where the user sends an identifier and password pair to the server. This information is sent un-encrypted. It is used in case a remote server does not support stronger authentication protocols such as EAP or CHAP. • Microsoft CHAP (MSCHAP-V2) is an encrypted authentication method based on Microsoft's challenge/response authentication protocol. 5. If you have a server certificate from a CA and wish to use it on the RADIUS server, select it from this pulldown menu. Only certificates imported to the switch will be available in the menu. To create a server certificate, select the Self Certificates screen from Certificate Mgmt in the navigation menu (see Creating Self Certificates). 6. You can also choose an imported CA Certificate to use on the RADIUS server. If using a server certificate signed by a CA, you will need to import that CA's root certificate using the CA certificates screen from the Certificate Mgmt menu. After a valid CA root certificate has been imported, it will be available from the CA Certificate pull-down menu. 7. DH Param File is required to support Cipher Suite v 0x13 (TLS_DHE_DSS_WITH_3DES_EDE_CBC_SHA) for EAP-TLS/TTLS. If this file does not exist on a WS2000, it is automatically created when the device is booted up. Use Create DH Param File to create the file as and when required. 8. Use the RADIUS Client Authentication table to set up multiple shared secrets based on the subnet or host that is trying to authenticate against the RADIUS server. Use the Add button to add entries to the list. Subnet/Host

This field contains the IP address of the subnet or host that will be authenticating with the RADIUS server.

Netmask

This field contains the netmask (subnet mask) of the subnet or host that will be authenticating with the RADIUS server.

Shared Secret

Set a shared secret to be used for each host or subnet that will be authenticating against the RADIUS server. The shared secret can be up to 7 characters in length.

6.3 Managing Digital Certificates A digital certificate is an electronic identification card that establishes your credentials when doing business or other transactions on the Web. It is issued by a certification authority (CA). It contains a name, a serial number, expiration dates, a copy of the certificate holder's public key (used for encrypting messages and digital signatures), and the digital signature of the certificate-issuing authority so that a recipient can verify that the certificate is real. The WS 2000 Wireless Switch uses digital certificates for VPN access authentication and user authentication. The application provides two mechanisms for defining/importing digital certificates: • CA certificates are those that a CA creates and signs with its own private key. These certificates are imported into the switch CA certificate library. (See Importing CA Certificates for directions.) • Self certificates are those that an organization creates a certificate request, sends it off to a Certificate Authority (CA) to be signed, and then imports the signed certificate into the management system. (See Creating Self Certificates for directions.)

6.3.1 Importing CA Certificates A certificate authority (CA) is a network authority that issues and manages security credentials and public keys for message encryption. The CA signs all digital certificates that it issues with its own private key. The corresponding public key is contained within the certificate and is called a CA certificate. A browser must contain this CA certificate in its “Trusted Root Library” so that it can trust certificates “signed” by the CA’s private key. Depending on the public key infrastructure implementation, the digital certificate includes the owner’s public key, the expiration date of the certificate, the owner’s name, and other information about the public key owner. The WS2000 Management System provides the means to import and maintain a set of CA certificates to be used as an authentication option for VPN access. To use the certificate for a VPN tunnel, define a tunnel and select the IKE settings to use either RSA or DES certificates. Before you import a certificate, you need to get one. Ask a CA for a certificate. They will typically send you the certificate information in an email message. You will need to import the content of the message into the WS2000 Network Management System. NOTE: Make sure that the WS2000 is time synchronized with an NTP server before importing a certificate to avoid issues with conflicting date/time stamps.

Administrator and User Access 6-17

To import a CA certificate perform the following steps: 1. Select [System Configuration] --> [Certificate Mgmt] --> CA Certificates from the left menu. The following screen appears.

2. Copy the content of the CA Certificate message into the clipboard and then click Paste from Clipboard. The content of the certificate will appear in the Import Root CA Certificate area. 3. Click the Import Root CA Certificate button to import it into the CA Certificate list. 4. Once in the list, select the certificate ID from the View Imported CA Certificates area to view information, such as the issuer name, subject, serial number, and data that the certificate expires. 5. Click the Apply button to save changes. To delete a certificate, select the Id from the menu and then click the Del (Delete) button.

6-18 WS2000 Wireless Switch System Reference Guide

6.3.2 Creating Self Certificates Self certificates are those for which the organization creates a certificate request, sends it off to a Certificate Authority (CA) to be signed, and then imports the signed certificate into the management system. To go through this process, select [System Configuration] --> [Certificate Mgmt] --> Self Certificates.

1. To create the certificate request, click the Add button. The Certificate Request screen appears.

2. Fill out the request form with the pertinent information. Only 4 fields are required: Key ID

Enter a name for the certificate to help distinguish between certificates. The name can be up to 7 characters in length.

Subject

This required field contains important information about the certificate. Contact the CA that will sign the certificate to determine the content of this field.

Administrator and User Access 6-19

Signature Algorithm

Indicate the signature algorithm to use for the certificate. The selection should match the VPN tunnel settings. • MD5-RSA: Message Digest 5 algorithm in combination with RSA encryption. • SHA1-RSA: Secure Hash Algorithm 1 in combination with RSA encryption.

Key Length

Indicate the desired length of the key. Possible values are 512, 1024, and 2048.

3. Fill in as many of the optional fields as desired or as required by the CA that will sign the certificate. The contact information is for the organization who is making the certificate request. The less obvious fields are: Email

Enter the email address to be used for identification purposes. Typically a CA requires either an email address, a domain name, or an IP address for identification purposes.

Domain Name

Enter the domain name to associate with the certificate. This field is often required by the CA.

IP Address

Enter the WAN IP of the WS 2000 Wireless Switch. Check with your CA to determine whether this information is necessary. Often it can be omitted if either the email or domain name information is provided.

4. When finished filling out the form, click Generate. The Certificate Request screen disappears and the ID of the certificate request that was just generated will appear in the Requests ID list of the Self Certificates window. 5. Click the Export Request button. The generated certificate request appears in the large text box. 6. Click Copy to Clipboard and the content of request to be sent to the CA will be copied to the clipboard. 7. Create an email to your CA, paste the content into the body of the message, and send it to the CA. 8. The CA will “sign” the certificate and send it back. At this point, copy the content from the email onto the clipboard. Then, click the Paste from Clipboard button and the content of the email will be displayed in the window. 9. Click the Import Certificate button to import the certificate and make it available for use as a VPN authentication option. The certificate ID will appear in the Signed list, where you can view information about it. 10.Apply your changes. To use the certificate for a VPN tunnel, first define a tunnel and select the IKE settings to use either RSA or DES certificates. NOTE: Note: If the switch is rebooted after a certificate request has been generated but before the signed certificate is imported, the import will not execute properly. Please do not reboot the switch during this interval.

7.7 Configuring Switch Redundancy The WS2000 Wireless Switch supports redundancy between two WS2000 Wireless Switch, allowing a standby switch to take over if the primary switch stop responding. Use the WS2000 Redundancy settings to configure the Operational State and Redundancy Mode for the switch.

7.7.1 Setting Up Switch Redundancy For each of the two switches, use the following procedure to set up redundancy. 1. Choose the redundancy mode in which the WS2000 Wireless Switch will operate in. Stand-alone The switch has no redundancy capabilities and operates independently of any other WS2000 switches on the network. This is the default setting.

Redundancy Two WS2000 switches are connected, with one set as a primary and the other as a standby. The primary switch will send heartbeat packets to the specified port of the standby switch at a specified interval. If the standby switch doesn't receive a heartbeat packet in a specified amount of time, it will take over as the primary switch.

2. When redundancy is selected as the operational state, specify whether the current switch is the primary or standby switch by selecting the appropriate Redundancy mode radio button. 3. When redundancy is selected as the operational state, in the Heartbeat Interval field specify the amount of time between heartbeat packets being sent or received between the two switches. 4. When redundancy is selected as the operational state, in the Revert Delay field specify the amount of time after not receiving a heartbeat packet before the standby switch will take over. 5. When redundancy is selected as the operational state, check the Preempt Standby box to prevent system standby on the redundant switches. 6. Click the check boxes in the Subnet Redundancy to select which subnets are enabled for redundancy. 7. Click Apply to save changes.

7.7.2 Redundancy Operations Status To see the Operational Mode status for switch redundancy, look at the bottom of the Redundancy screen. Click the Refresh button to update the Operational Mode status.

7.8 Updating the WS2000 Wireless Switch’s Firmware From time to time, Motorola releases updates to the WS2000 Wireless Switch’s firmware. These updates include: • Information about how to communicate with newly released Access Ports • Updates for security issues that have been identified • Fixes to any software problems that have been identified

7.8.1 Checking for and Downloading Firmware Updates The switch administrator should check for firmware updates for the WS2000 Wireless Switch on a monthly basis, as follows: 1. Select [System Configuration] --> [Cfg/Firmware Mgt.] --> Firmware Update from the menu on the left.

2. Examine the Version field to record the version number of the currently loaded software. It should be something like 2.0.0.0-20 3. Go to the web site http://www.motorola.com/services/downloads/ and select the link to the WS2000 Wireless Switch. 4. Compare the WS2000 Version value with the most recent version listed on the site. All updates will be listed along with a description of what the update contains. 5. Check to see if an administrator has already downloaded the file. It might already be on an FTP server at the site. If not, download the update from http://www.motorola.com/services/downloads/. Put the file

7-8 WS2000 Wireless Switch System Reference Guide

on an FTP server, on a system with a TFTP server, or on a CompactFlash card that is compatible with the switch.

7.8.2 Performing the Firmware Update To perform the update, the update file must be available from an FTP or TFTP site, or it must be on the Compact Flash (CF) card in the CF slot of the switch. The administrator supplies the site information and the WS2000 Network Management System will perform the update for the administrator. 1. Save the WS2000 Wireless Switchâ&#x20AC;&#x2122;s current configuration settings ([System Configuration] --> Config Import/Export) 2. Select [System Configuration] --> Firmware Update from the left menu to view the Firmware Update screen. 3. Specify the Filename of the firmware file with the update (such as WS_22343.bin). 4. Specify the Boot Device for the WS2000. The WS2000 boots from the selected Boot Device. Select the option from one of Onboard Flash or CF Card. When CF Card is selected as the boot device, select the active partition as either the primary or the secondary partition from the CF Active Partition drop down list. When a partition is selected as the active partition, the new firmware will be installed in that partition on the CF card. This enables the CF card to host 2 different WS2000 firmware images in addition to the one present in the onboard flash of the switch. 5. Specify the Bind Interface. Bind interface is used if the FTP/TFTP/SFTP server is located beyond the VPN tunnel. In such a case, the bind interface should be the subnet on the WS2000 that is configured as the local subnet for the VPN tunnel. Select Bind Interface as none if the FTP/TFTP/SFTP server is not located beyond a VPN tunnel. 6. Specify a folder pathname for an FTP login, if necessary. 7. Select one of the FTP, TFTP, SFTP or CF Card radio buttons, as appropriate. If FTP is selected: 1. Specify whether the FTP server is on the WAN or is on one of the subnets associated with the switch by selecting the appropriate choice from the FTP Server on drop-down menu to the right of the radio button. 2. Specify the IP Address of the FTP server that has the update. 3. Specify a Username and Password that will allow the FTP login and access to the file. If TFTP is selected: 1. Specify whether the TFTP server is on the WAN or is on one of the subnets associated with the switch by selecting the appropriate choice from the TFTP Server on drop-down menu to the right of the radio button. 2. Specify the IP Address of the TFTP server that has the update. NOTE: When using TFTP as the upgrade method, be sure the TFTP server you are using supports files larger than 16MB. The WS2000â&#x20AC;&#x2122;s firmware files are over 20MB in size and will cause the upgrade to fail if your TFTP server does not support files larger than 16MB. If SFTP is selected: 1. Specify the IP Address of the SFTP server that has the update.

Switch Administration 7-9

2. Specify the Username and Password that will allow the SFTP login and access to the file. The Username and Password fields are located under FTP. 3. For firmware upgrade to work, a CF card must be inserted in the WS2000’s CF card slot. Also, the CF card must have atleast 64 MB of free space. When SFTP is used to upgrade the firmware, the firmware image is first downloaded to the CF card. The switch reboots and the firmware is updated automatically from the CF card. NOTE: Upgrading firmware using SFTP takes longer than when updating from either FTP or TFTP. This is primarily due to the process as the firmware is downloaded and written to the CF card. I/O opration on CF card is slow. Once the firmware is written to the CF card, the firmware update is performed from it. If CF Card is selected: 1. Click the Display CF button to open a dialogue where you can browse the Compact Flash card’s file system to find or verify the firmware file and path. NOTE: Partitioned CF cards will not be read by WS2000 running firmware versions that are lower than version 2.3. Similarly, CF cards partitioned by the ‘exec cfpartition’ command on a WS2000 running version 2.4 will not be read by WS2000 running version 2.2 or below. Click the Format CF button to format the compact flash card before storing the firmware file on it. To complete the update: 1. Click the Perform Update button to initiate the firmware update for the switch. The update process will take a few minutes. 2. After the switch reboots, return to the Firmware Update screen. Read the Status field to verify that the firmware update completed successfully. The Version number at the top of the screen should have been updated. 3. Confirm that the wireless switch’s configuration settings are the same as prior to the update. If not, restore the settings.

7.8.3 Formatting a Compact Flash Card If you need to erase the contents of a Compact Flash card you can do so on the Firmware Update screen. WARNING! Formatting a Compact Flash card will erase all data on the card. There is no undo option for formatting cards. Be sure that you do not need any data on the Compact Flash card before formatting it. To format a Compact Flash card: 1. Navigate to [System Configuration]--> Cfg/Firmware Mgt--> Firmware Update screen. 2. Verify that the Compact Flash card is firmly seated in the WS2000’s Compact Flash slot. 3. Click the Format CF button. 4. Click Yes to continue formatting the card.

7-10 WS2000 Wireless Switch System Reference Guide

WARNING! Sometimes you might encounter an issue with mounting CF cards that have been formatted on a Windows/XP machine. To resolve this issue, reset the WS2000 with the CF card inserted. Go to the boot prompt. From the boot prompt enter the following commands: cf fill 0 0 cf fill 100 0 cf fill 200 0 You can then take the card and format it using a Windows machine using FAT32. Any card formatted on a Linux machine does not have this issue. NOTE: Use the â&#x20AC;&#x2DC;exec cfpartitionâ&#x20AC;&#x2122; command from the boot prompt to create a CF card with multiple partitions. This command creates a CF card with 1 VFAT partition and 2 LINUX partitions.

7.8.4 Limitation of File System on the Compact Flash Card The Compact Flash (CF) card users VFAT (FAT16) file system. This file system can at the most support 512 root directory entries, where each directory entry can either be a file or a folder (directory). If long file names are used (other than xxxxxxxx.xxx (<filename>.<ext>) format) , then the number of entries are less than 512. Once the limit of 512 is reached, no more files or directories can be added. If the 512 entry limit is reached, it can be overcome by deleting a file and creating a folder (directory). However, it is suggested to keep number of files or folders (directories) in the root folder of the CF card low. The limit of 512 entries is applicable to every directory created.

7.8.5 Setting Up DHCP Options for Firmware Upload It is also possible to configure the switch to receive firmware and configuration files automatically from a server using the Dynamic Host Configuration Protocol (DHCP). This features allows quick and automatic rollouts of new configurations or firmware updates across the network without manually updating each switch. Select [System Configuration] --> [Cfg/Firmware Mgt] --> DHCP Options (Sys Update) to configure the switch to accept DHCL downloads.

Switch Administration 7-11

7.8.5.1 Setting Up the Switch 1. Check Enable Automatic Firmware Update to allow the WS2000 Wireless Switch to automatically receive firmware updates from a server using the DHCP protocol. By default this option is disabled. 2. Check Enable Automatic Configuration Update to allow the WS2000 to automatically receive configuration file updates from a server using DHCP. By default this option is disabled. 3. Set the Auto Upgrade Interval (in seconds) for the WS2000 to check the server for automatic updates. 4. Use the Interface menu to select the interface from which Firmware and Configuration updates will be received. This interface can be either the WAN port or any of the configured subnets on the switch. By default this value is set to WAN. 5. Optional: If you wish to change or specify a DHCP Vendor Class Id enter it here. DHCP Vendor class ID is used by the onboard DHCP clients as a unique identifier for Firmware/Config upgrade parameters. The external DHCP server which handles the DHCP client needs to be configured with this option to provide TFTP/FTP server IP, firmware file name and config file to facilitate WS2000 for Auto FW/Config upgrade. Any string provided in the text field will be prefixed with a â&#x20AC;&#x153;SymbolWS.WS2Kâ&#x20AC;? string. 6. Navigate to the Firmware or Config Import/Export screen depending on whether you are setting up the automatic firmware download or configuration settings download. Set the TFTP server IP address to the IP address of the server what will do the download. Also set the name of the file to download.

7.8.5.2 Setting Up the DHCP Server The external DHCP server will also needs to be configured appropriately. On a Windows server, you will need to select the appropriate options in the server setup. For a Linux server, edit the /etc/dhcpd.conf file to have the appropriate settings.

Select the bind interface from the Bind Interface drop down list. This interface is used to reach the FTP/ TFTP server for firmware update. Select, as the bind interface, the subnet that is configured as the local subnet for the VPN tunnel and on which the FTP/TFTP server resides. 7. To restrict the maximum size of the sensor firmware image, use the Max size of sensor file. Use this value to restrict the file size for the sensor firmware file.

7.10.2 Updating the Sensor Firmware To update the sensor firmware, use the FTP, SFTP or TFTP buttons on the screen. Select the appropriate server to update the sensor firmware from. A warning dialog appears.

Click Yes to proceed with sensor firmware update. Once the sensor firmware is updated, a status is shown in the Sensor Firmware Update screen.

7.11 Configuring SNMP The Simple Network Management Protocol (SNMP) facilitates the exchange of management information between network devices. SNMP allows an administrator to manage network performance, find and solve network problems, and plan for network growth. The WS2000 Wireless Switch includes SNMP management functions for gathering information from its network components, and communicating that information to specific users. There are four different SNMP screens. • Use the SNMP Access screen to define SNMP v1/v2c community definitions and SNMP v3 user definitions associated with access. • Use the SNMP Trap Configuration screen to configure to define SNMP v1/v2c community definitions and SNMP v3 user definitions associated with the traps themselves. Trap configuration depends on the network machine that receives the generated traps. • Use the SNMP Traps screen to enable system, network, SNMP, mobile unit, and Access Port traps. • Use the SNMP Rate Traps screen to enable traps by setting RF Rate thresholds.

Switch Administration 7-17

Select [System Configuration] --> SNMP Access from the left menu to set up SNMP service.

7.11.1 Setting the SNMP Version Configuration The SNMP Access screen allows the administrator to define SNMP v1/v2c community definitions and SNMP v3 user definitions. SNMP v1 and v2c provide a strong network management system, but their security is relatively weak. SNMP v3 provides greatly enhanced security protocols. SNMP v3 encrypts transmissions and provides authentication for users generating requests.

7.11.1.1 Setting Up SNMP v1/v2c Community Definitions SNMP v1/v2c community definitions allow read-only or read/write access to switch-management information, as appropriate. The SNMP community, in this case, includes users whose IP addresses are specified on the SNMP Access Control subscreen. A read-only community string allows a remote device to retrieve information, while a read/write community string also allows a remote device to modify settings. Set up a read/write definition to facilitate full access by the administrator. 1. To create a new community definition, click the Add button in the SNMP v1/v2c Community Configuration area. 2. Type in a site-appropriate name for the community. 3. Click in the OID cell of the table. Either use the OID (Object Identifier) pull-down menu to select the default OID or type in an OID number into the field. (The format is in a numerical dot notation, and valid numbers can be found within the MIB.) If is selected, the community will have access to all the OIDs (SNMP parameters) in the SNMP Management Information Base (MIB) file. If a custom OID is entered, the administrator can allow access to specific OIDs in the MIB to certain communities. 4. Use the Access pull-down menu to specify read-only (R) access or read/write (RW) access for the community. Read-only access allows a remote device to retrieve switch information, while read/write access also allows a remote device to modify switch settings. 5. Continue to the Setting Up the Access Control List section in this document.

7-18 WS2000 Wireless Switch System Reference Guide

7.11.1.2 Setting Up SNMP v3 Community Definitions Setting up the v3 user definition is very similar to the v1/v2c community definitions. The difference is the addition of a user security level and a user password. 1. To create a new SNMP v3 user definition, click the Add button in the SNMP v3 User Definitions area. 2. Specify a user name in the Username field. 3. Select a security level from the Security pull-down menu. Select from the following choices: noAuth

(no authorization) Allows the user to access SNMP without authorization or encryption

AuthNoPriv

(authorization without privacy) Requires the user to login, however no encryption is used

AuthPriv

(authorization with privacy) Requires the user to login and encryption is used

4. Click in the OID cell of the table. Either use the OID (Object Identifier) pull-down menu to select the default OID or type in an OID number into the field. (The format is in a numerical dot notation, and valid numbers can be found within the MIB.) If is selected, the community will have access to all the OIDs (SNMP parameters) in the SNMP Management Information Base (MIB) file. If a custom OID is entered, the administrator can allow access to specific OIDs in the MIB to certain communities. 5. Click the Password button in the cell and the Password Settings screen appears. 1.Select an Authentication Algorithm from the drop-down menu, either MD5 or SHA1. 2.Type in an Authentication Password. 3.Select a Privacy Algorithm from the drop-down menu. The options include: â&#x20AC;˘ DES â&#x20AC;˘ AES 128-bit 4.Type in a Privacy Password that matches the algorithm. 5.Click Ok, when done. 6. Use the Access pull-down menu to specify read-only (R) access or read/write (RW) access for the community. Read-only access allows a remote device to retrieve switch information, while read/write access also allows a remote device to modify switch settings. 7. Follow the directions for setting up the Access Control List (below).

Switch Administration 7-19

7.11.2 Setting Up the Access Control List To set up the Access Control list as specified by a range of IP addresses, click the SNMP Access Control button at the bottom of the SNMP Access screen. The SNMP Access Control screen appears: 1. Click the Add button to create a new entry in the Access Control table. 2. Specify the IP address for the user(s) that have access. Enter an IP address only in the Starting IP Address column to specify an address for a single SNMP user. Enter both the Starting IP Address and Ending IP Address columns to specify a range of addresses for SNMP users. 3. Click Ok to save changes and return to the SNMP Access screen.

7.11.3 Setting the Trap Configuration To set the trap notification destination for SNMP, select [System Configuration] --> SNMP Access --> SNMP Trap Configuration from the left menu.

7.11.4 Setting the Trap Configuration for SNMP v1/v2c To set the trap notification destination for the SNMP v1/v2c servers, add one or more entries to SNMP v1/ v2c Trap Configuration table. 1. Click the Add button to add a new entry to the table. 2. Specify a Destination IP addresses for the systems that will receive notification when an SNMP trap is generated.

7-20 WS2000 Wireless Switch System Reference Guide

3. Specify a destination User Datagram Protocol (UDP) port for receiving the traps that are sent by SNMP agents. UDP offers direct connection for sending and receiving datagrams over an IP network. 4. Specify a Community name that matches one of the community names added on the SNMP Access screen. 5. Select the appropriate SNMP Version (v1 or v2) from the pull-down menu for this particular SNMP server. 6. Click the Apply button to save the entries.

7.11.5 Setting the Trap Configuration for SNMP V3 To set the trap notification destination for the SNMP v3 servers, add one or more entries to SNMP v3 Trap Configuration table. 1. Click the Add button to add a new entry to the table. 2. Specify a Destination IP addresses for the systems that will receive notification when an SNMP trap is generated. 3. Specify a destination User Datagram Protocol (UDP) port for receiving the traps that are sent by SNMP agents. UDP offers direct connection for sending and receiving datagrams over an IP network. 4. Specify a Username that matches one of the user names added on the SNMP Access screen. 5. Specify a Security level from noAuth (no authorization required), AuthNoPriv (authorization without encryption), or AuthPriv (authorization with encryption). 6. Specify a password for the user. NOTE: When entering the same username on the SNMP Traps and SNMP Access screens, the password entered on the SNMP Traps page will overwrite the password entered on the SNMP Access page. To avoid this problem enter the same password on both pages. 7. Click the Apply button to save changes

7.11.6 Selecting Traps The SMNP Trap screen allow you to specify the types of network events that generate traps, and who to notify regarding the events. SNMP traps are generated according to predefined types of network events that are considered important to manage. This information is asynchronously reported to the switchâ&#x20AC;&#x2122;s SNMP network-management system by switch-managed entities. Notification is sent to the responsible individuals whose IP addresses are listed for trap notification.

3. Click the Apply button to save the trap settings. 4. It is necessary to tell the switch where to send the notifications. Make sure to set the trap configuration to indicate where to send the trap notifications.

7.11.7 Setting RF Traps A screen is also available to specify traps caused when certain rates of activities either exceed or drop below a specified threshold. To set rate traps, select [System Configuration] --> SNMP Access --> SNMP RF Traps from the left menu.

1. Select the threshold type for which you want a rate trap, such as Pkts/sec. 2. Determine whether you want the rate to apply to Switch (the switch as a whole), Wlan (for each WLAN enabled), Ap (each associated Access Port), or Mu (each mobile unit connected to the switch). 3. Type in the threshold rate into the field associated with the selected object. 4. Traps are only generated for those field where numbers exist. Explanation of the different threshold types are listed below. Pkts/s

The maximum threshold for the number of packets per second before a trap is sent.

Throughput

The maximum threshold for the total throughput in Mbps (Megabits per second) for each of the devices before a trap is sent.

Average Bit Speed

The minimum threshold for the average bit speed in Mbps (Megabits per second) for each of the devices before a trap is sent.

% Non-Unicast

The maximum threshold for the total percentage of packets that are non-unicast for each of the devices before a trap is sent. Non-unicast packets include broadcast and multi-cast traffic.

Average Signal

The minimum threshold for the average signal strength in dBm for each of the devices before a trap is sent.

7-24 WS2000 Wireless Switch System Reference Guide

Average Retries

The maximum threshold for the average number of retries for each of the devices before a trap is sent.

% Gave Up

The maximum threshold for the total percentage of packets that are given up for each of the devices before a trap is sent.

% Undecryptable

The maximum threshold for the total percentage of packets that are undecryptable for each of the devices before a trap is sent. Undecryptable packets can be the result of corrupt packets, bad CRC checks, or incomplete packets.

Associated MUs

The maximum threshold for the total number of MUs associated with each of the devices before a trap is sent.

Enter the minimum number of packets that must pass through the device before an SNMP rate trap will be sent. It is recommended to set this value no less than 1000.

7.12 Specifying a Network Time Protocol (NTP) Server Network Time Protocol (NTP) manages time and clock synchronization in a network environment. The switch, which acts as an NTP client, periodically synchronizes its clock with a master clock on an NTP server. Time synchronization is typically optional (although recommended) for the switchâ&#x20AC;&#x2122;s network operations; however, for sites using Kerberos authentication, time synchronization is required. Kerberos must synchronize the clocks of its Key Distribution Center (KDC) server(s). Select [System Configuration] --> NTP Servers from the left menu to enable NTP. The NTP Server screen appars.

1. The field on the left of the Current Time area displays what the switch believes is the current time. Click the Refresh button to update that time. If an NTP server is configured, the switch will go out to the network to update its current time. 2. Specify a time zone by selecting the appropriate zone from the Time Zone list. 3. To set the time manually, click the Set Date/Time button. A sub-window displays where you can set the WS2000â&#x20AC;&#x2122;s time.

Switch Administration 7-25

NOTE: When NTP is enabled on the WS2000, you will not be able to set time manually.

4. To enable time service on the switch, check the Enable NTP on check box and continue with the rest of the steps below. 5. Specify a Preferred Time Server, and optionally a First Alternate Time Server and a Second Alternate Time Server by specifying the IP address and Port for the time service for each server. The default port is 123. The more NTP servers specified, the greatest assurance there is of uninterrupted time synchronization. 6. Specify a Synchronization Interval (in minutes). By default, the switch will synchronize the time every 15 minutes. 7. Click the Apply button to save any changes made on this screen.

7-26 WS2000 Wireless Switch System Reference Guide

7.13 Setting Up and Viewing the System Log The WS2000 Network Management System keeps a log of the events that happen on the switch. The switch has a modest of amount of memory to store events. If the administrator wishes to keep a more complete event history, the administrator needs to enable a log server. To view the log or set up a log server, select [System Configuration] --> Logging Configuration from the left menu.

7.13.1 Viewing the Log on the Switch To save a log of the most recent events that are retained on the switch, click the View button. The system will display a prompt asking for the administrator password. After the password has been entered, click the Get File button and a dialogue will be displayed with buttons to Open or Save the log.txt file. Click Save and specify a location to save the file. To view the saved log.txt file on a Microsoft Windows based computer use the WordPad application. Viewing the log file with Notepad, the default text file view on most Windows based computers, will not properly display the formatting of the log file.

7.13.2 Setting Up a Log Server To keep a complete history of the events that are logged by the switch, the administrator needs to set up an external system log on a server. The server listens for incoming switch-generated syslog messages on a UDP port (514 by default), and then decodes the messages into a log file appropriate for viewing and printing. Events are categorized into eight levels (0 through 7), with the lowest numbers representing the most critical issues. 1. Set the level of the errors to be logged from the Logging Level drop-down menu. All events associated with the selected level and events with levels lower than the selection will be recorded. 2. Check the Enable logging in to an external syslog server check box to enable logging. 3. Specify the Syslog server IP address for the server that will store the log.

Switch Administration 7-27

4. Check the Enable logging to CF check box to enable logging of events to a CF card on the switch. This is useful when the connection to the Syslog server is lost due to network disturbances or any other cause. When enabled, the event log is written to the CF card when the Syslog server is not available for any reason. When the Syslog server comes back on line, the logging is automatically done to the server. 5. Select Apply to save the changes. 6. Select Network Configuration --> Subnet Access. Work through all the combinations of subnet-toWAN accesses to ensure that DNS communications are allowed. (UDP must be enabled to save the log entries.)

7.14 Commands to unmount a CF card To unmount a CF card used to load firmware use these commands from the console. admin> system admin(system)> exec cfumount

To see the contents of the CF card use these commands from the console. admin> system admin(system)> cf admin(system.cf)> ls . .. mf12.bin mf_02020200003R.bin admin(system.cf)>

You can also use these commands to view the contents of the CF card. admin(system)> exec df â&#x20AC;&#x201C;h /mnt/cf

7.15 Sample Configuration File All the configuration settings for the WS2000 Wireless Switch can be saved to a configuration file and then either imported back into the same switch or transferred to other switches. Below is a sample configuration file that has been annotated using comment lines. All comment lines begin with // and are blue in color. The configuration file is organized by function area, and most areas correspond directly to a menu item. // // WS2000 Configuration Command Script // System Firmware Version: 2.4.3.0-017R // system ws2000 // WS2000 menu set name WS2000 set loc \0 set email \0 set cc us

8-2 WS2000 Wireless Switch System Reference Guide

8.1 Overview The hotspot feature enables the WS2000 Wireless Switch to act as a single on-site solution to provide wireless LAN hotspots and management. The hotspot access controller enables hotspot operators to provide user authentication and accounting without a special client application. It enables an web browser as a secure authentication device. Instead of relying on the built-in security features of 802.11 to control privileges to an access port, you can configure a WLAN as an open network with hotspot authentication. The WS2000 Wireless Switch provides an IP address to the user through its built-in DHCP server, authenticates the user, and enables the user to access the Internet.

8.1.1 Requirements The hotspot feature requires the following:â&#x20AC;&#x2DC; HTTP redirection

Redirects unauthenticated users to a specific page specified by the Hotspot provider.

User authentication

Authenticates users using a RADIUS server.

Walled garden support

Enables a list of IP address (not domain names) to be accessed without authentication.

Billing system integration

Sends accounting records to a RADIUS accounting server.

8.2 Configuring Hotspot To configure the hotspot access controller on the WS2000 Wireless Switch: 1.

8.2.2 Set Hotspot Configuration Hotspots can be configured from the <WLAN Name> Hotspot Config screen. This screen allows you to configure the different parameters to enable users to use the hotspots.

To configure the hotspot for a WLAN: 1. Set the HTTP Redirection mode to either http or https by selecting the appropriate option. When a user successfully logs on using the hotspot, the user is redirected to a welcome screen. This selection decides the redirection mode. 2. Set the location of the files the user is redirected to by selecting one of the Use Default Files, Use CF Card, or Use External URL options. To use the standard redirect HTML files, select the Use Default Files option. To use redirect HTML files stored on a CF card loaded to the switch, use Use CF Card option. When selected, the CF Card Files area is enabled. To use redirect HTML files stored on a different location on the local network, use the Use External URL option. When this option is selected, the External URL area is enabled. Radius Server Configuration 3. By default, hotspot user authentication is performed using a RADIUS server. This server could be on the network or you can use the onboard/local RADIUS server. To use a RADIUS server located on the network, enter the appropriate information in the Radius Configuration area. You must enter the IP Address, Port, and the Common Secret for at least the

primary RADIUS server. To authenticate a hotspot user with a RADIUS server through a VPN tunnel select the bind interface from the Bind Intf (for Pri Server) drop down. If the RADIUS server is on a network accessible through a VPN tunnel, then the tunnel must be configured. The bind interface should be the same as the Local Subnet configured for the VPN tunnel. Entering information for the secondary RADIUS server is optional. To authenticate a hotspot user with a RADIUS server, select the authentication mode from the Radius auth-mode drop down. You can use either PAP or CHAP as the authentication mode. To use the RADIUS server located on the WS2000, click the Use Local Radius button. This sets the value of the Primary RADIUS Server IP to 127.0.0.1, the port to 1812. Enter the common secret for access in the Pri Secret field. You can also provide information for an external secondary RADIUS server. Radius Accounting Logs 4. The Radius Accounting area provides a feature by which user logins and logouts can be logged. This user accounting information can be sent to an external RADIUS server or to the installed CF card. using the onboard RADIUS server. To enable logging of RADIUS accounting to the CF card, select the Enable Accounting (Save to CF Card) option. Enter the Timeout value which is the duration (in seconds) for retransmitting the accounting request to the RADIUS server if no response is received from the server. The timeout value should be between 1255 sec. Enter the Retries value which is the number of times the accounting request is sent to the RADIUS server if no response is received, before logging is done on to the CF Card. The value should be between 1-10. White List Entries 5. The White List is a list of URLs the hotspot users can access without authentication. A maximum of 10 URLs can be created for each WLAN. Click White List Entries button to enter and manage White List entries for the WLAN.

8.2.3 Setting the User Access Policy The RADIUS Access Policy screen allows you to set WLAN access based on a user group defined on the User Database screen. Select [User Authentication] --> RADIUS Server --> Access Policy to set group access.

8.2.4 Defining the Hotspot State of a Mobile Unit When configured as a hotspot, the switch tracks the hotspot-state of each mobile unit associated with the hotspot. The server maintains a list of all mobile units associated and tracks the state of these mobile units. Mobile Units in a hotspot have one the following two states: • REDIRECT state—The associated mobile unit enters the REDIRECT state after 802.11 authentication and association. The mobile unit remains in this state until it successfully authenticates through the RADIUS server. After the mobile unit logs-off from the hotspot, it moves into the REDIRECT State. • RADIUS AUTHENTICATED state—The mobile unit moves into the RADIUS AUTHENTICATED state after it successfully authenticates through the RADIUS server. The RADIUS server provides the trigger to move the state of the mobile unit from REDIRECT to RADIUS AUTHENTICATED. There is a dedicated socket connection between the wireless switch and an the RADIUS server for this purpose. After the RADIUS server successfully authenticates the mobile unit, it sends a trigger to the wireless switch to change the hotspot-state of the mobile unit to RADIUS-AUTHENTICATED.

Configuring HotSpot 8-9

When the mobile unit requests the RADIUS server to log out, the RADIUS server again sends a trigger to the wireless switch to change the state of the mobile unit to REDIRECT.

8.2.5 Handling log-in and redirection When a client requests a URL from a web server, the login handler returns an HTTP redirection status code in the range 300-399 (for example, 301 Moved Permanently), which indicates to the browser that it should look for the page at another URL. This other URL can be a local or remote login page (based on the hotspot configuration). The login page URL is specified in the location HTTP header. After the response with status code 301 Moved Permanently, the clientâ&#x20AC;&#x2122;s browser issues a request for the URL specified in the response header. The clientâ&#x20AC;&#x2122;s browser, then displays the WS2000 login page. To host a login page on the external web server, the IP address of that web server should be in the White list (list of IP addresses that are allowed to access the server) configuration. Ensure that the login page is designed so that the submit action always posts the login data on the WS2000 Wireless Switch. When the login information is submitted to the WS2000 Wireless Switch, the login handler runs a CGI script that uses this data as input and sends the user the response from the CGI script.

8.2.6 Authentication (RADIUS) The CGI script has a RADIUS client built in it, which receives the posted login data and initiates RADIUS authentication. If the RADIUS authentication for that user is successful, the CGI script does the following: 1. Sends a command to wireless switch to change the MU state from REDIRECT to RADIUSAUTHENTICATED. 2. Replies back to the login handler to generate an HTTP redirection response for Welcome page. 3. Starts the RADIUS accounting for the user. The Welcome page will contain Logout button, which user can click at any point to logout from the system. Again the Remote Welcome page needs to be setup such that the logout request should be sent to WS2000. If the RADIUS authentication for that user is failed the CGI script will reply back to the Login Handler to generate an HTTP redirection response for Fail page. 4. Click the Logout button on the Welcome page to log out of the switch at any point. Upon logout another CGI script is executed. The CGI script will use REMOTE_ADDR environment variable to get the IP address of the requester and verify its MAC address from ARP table. Then CGI script will stop the RADIUS accounting for that client and sends a command to wireless switch to change the MU state back to REDIRECT. To create new guest hotspot users see Chapter 6, Adding New Guest Users Quickly.

8-10 WS2000 Wireless Switch System Reference Guide

8.2.7 Accounting (RADIUS) Upon successful login a CGI script will generate an Accounting Start packet describing the type of service being delivered and the client. The script will then send that information to the RADIUS Accounting server, which will reply with an acknowledgement that the packet has been received. If a client logs out or an MU is dis-associated, an Accounting Stop packet will be generated describing the type of service that was delivered, the statistics, and the elapsed time. That packet will be sent to the RADIUS accounting server, which replies with an acknowledgement that the packet has been received.

9.1 Overview When browsing web sites or sending E-mail messages a domain name is used. For example, the URL www.yahoo.com and the e-mail address user@yahoo.com contains the domain name yahoo.com. Domain names allow users to remember the address to a site without knowing the IP address. For traffic to be routed on a network those domain names must first be converted to an IP address. When a domain name is entered, the domain is translated to an IP address by a Domain Name Server (DNS). DNS translation poses the following challenges: â&#x20AC;˘ There are a limited number of IP addresses currently available. â&#x20AC;˘ Domain names and IP addresses are created and changed everyday. Dynamic Domain Name System (DDNS) enables you to link a domain name to a changing IP address. When you connect to the Internet, your Internet service provider uses Dynamic Host Configuration Protocol (DHCP) and assigns the domain an unused IP address from a set pool of IP addresses. This IP address is only used for the duration of this specific connection. This method of dynamically assigning addresses, increases the pool of available IP addresses. The DDNS service maintains a database to connect a domain name to an IP address on the Internet. Because the IP addresses change, it is necessary to update the DNS database with the current IP address for a given domain name. The DDNS service performs these updates. Enabling Dynamic DNS will allow domain name information to be updated when the IP address associated with that domain changes. When a MU associates and gets and IP address from the DHCP server the DHCP server then updates the DNS server with the IP allocated to the corresponding hostname.

9.2 Enabling DDNS Dynamic DNS is configured on a per-subnet basis and requires the subnet to be configured as a DHCP Server. DDNS is then enabled and configured in the Advanced DHCP Server screen for the corresponding subnet. 1. From the Subnet screen for the desired subnet select the This interface is a DHCP Server option.

Using DDNS 9-3

2. Enter a range of IPs in the Address Assignment Range fields. 3. Click the Advanced DHCP Server button to open the Advanced DHCP window.

4. In the Advanced DHCP Server window check the box next to Enable Dynamic DNS. 5. Select either Single User Class Option or Multiple User Class Option depending on the settings of your DHCP clients. Any DHCP client can send the User Class Id either in the Single or Multiple user class ID format. The Single or Multiple User class option is provided to enable the switch to interpret the correct format in which the user class ID is sent by the client. The switch then retrieves the correct value of the user class ID sent by the DHCP client based on the selected format. This same user class ID format is used for the DDNS messages. 6. Enter IP Addresses in Primary DNS Server, Secondary DNS Server and Default Gateway and click the Ok button to return the Subnet configuration screen. 7. Click the Apply button on the Subnet configuration screen to save the changes and activate DDNS for that subnet.

9-4 WS2000 Wireless Switch System Reference Guide

9.3 Updating DNS Entries using DDNS Once DDNS has been configured and enabled for a subnet, it is possible to manually refresh the DNS entries for all active DHCP clients on a single subnet or on all active subnets.

9.3.1 Updating DNS Entries for a Single Subnets The DNS entries for a single subnet can be updated using the following steps. 1. Select the subnet you wish to refresh from the menu tree on the left side of the screen.

2. From the Subnet configuration screen click the Update DNS button located in the DHCP section of the screen. After the Update DNS button has been clicked, an ADD DNS message for all the active leases on the DHCP server for that subnet is sent to the DNS server. A DELETE DNS message for all the inactive leases on the DHCP server for that subnet is sent to the DNS server.

Using DDNS 9-5

9.3.2 Updating DNS Entries for All Active Subnets The DNS entries for all active subnets can be updated using the following steps. 1. Select LAN from menu tree on the left side of the screen.

2. From the DNS Update section of the screen click the Update DNS for All Subnets button located in the DHCP section of the screen. After the Update DNS for All Subnets button has been clicked, an ADD DNS message for all the active leases on the DHCP servers for all active subnets is sent to the DNS server. A DELETE DNS message for all the inactive leases on the DHCP server for all active subnets is sent to the DNS server.

10.1 Overview Earlier versions of WS2000 had a limit of 31 VLAN IDs (IDs 1-31) due to LAN port switch hardware limitations. It was difficult to seamless integrate the WS2000 with existing network topology of VLANs with VLAN IDs greater than 31. To enable easier integration into networks with existing VLAN infrastructure, you can now configure the existing WAN port as a Trunk-Port and the user can configure any VLAN-IDs in the range 1-4094. With this setup, the WAN port can be configured either as a TRUNK port or as a WAN Link.

10.1.1 Assigning VLAN Tags to Packets VLAN tag assignment to packets is achieved as follows: • Wired hosts are assigned VLANs based on the Port to which they are connected. • Wireless hosts, upon successful authentication, are assigned VLANs based on the WLAN through which they authenticate. The WS2000 then maintains a table to store the hosts to VLAN mapping information. Packets coming in from the LAN ports are handled as follows: • For unicast packets destined to hosts on the same VLAN, the LAN switch handles the packet if both the hosts are wired. • For unicast packets destined to hosts on different VLANs, the WS2000 switches the packet. • For broadcast packets, the same packet is duplicated and forwarded to all ports and WLANs on the same VLAN.

10.1.2 Installation Considerations and Default VLAN Settings By default the WAN port is configured as a WAN LINK. This port has a default VLAN ID of 1. After upgrading the WS2000 to version 2.1 or above, the WAN port can be configured as either a WAN Link or as a TRUNK port. The user can configure any VLAN IDs between 1 and 4094. The Factory Setting for the WS2000 Version 2.1 would be as follows: • Native VLAN by default is VLAN ID 1 • No Trunk Port is configured. • The WAN port is configured as a WAN Link. • No VLANs are enabled for Trunking.

Trunking VLANs Through the WAN Port 10-3

10.2 Configuring VLAN Trunking Use the following steps to configure VLAN trunking on the WAN port. 1. Select Network Configuration --> VLAN to open the VLAN Configuration screen.

1. Use the pull-down menu to select a VLAN Type for this switch. The two options are User Based and Port Based. Port-based VLANs partitions traffic based on port on which the packet is received. The switch inspects each packet, extracts the port on which it was received (from control information provided by the driver) and processes the packet based on the port. The port is mapped to a subnet and each subnet is mapped to a single VLAN. The switch processes the packet based on this mapping. User-based VLAN traffic classification is performed only for Wireless traffic. The VLAN for a particular MU is identified when the MU authenticates itself with the RADIUS server using a user ID and password. The RADIUS server provides the VLAN ID corresponding to this MU and User ID information combination. The switch processes the packet based on the VLAN ID provided by the RADIUS server. For wired traffic, the classification as done in Port-based VLANs applies. 2. Use the pull-down menu to select a Trunk Port for the switch. Only the WAN port can be configured as the Trunk Port. 3. Enter the Default VLAN ID to be used for packets that do not have the VLAN tag inserted. The default VLAN ID must be one of the IDs assigned to the subnets if the VLAN Type is Port Based. If the VLAN Type is User Based, then the Default VLAN ID must be one from the Allowed VLANs list. 4. For each enabled Subnet, enter the VLAN ID. 5. Enter a list of allowed VLANs between 1 and 4094 in the Allowed VLANs box. The VLANs in this list will be allowed access through the WAN port. When entering multiple VLAN IDs, separate each ID with a comma. When entering a range of VLAN IDs, separate the starting and ending values with a â&#x20AC;&#x153;-â&#x20AC;?.

10-4 WS2000 Wireless Switch System Reference Guide

6. To enable filtering using IP, check the Enable IP Filtering check box. This option is only available only when Trunk Port is set to Wan. To add an IP filter, click IP Filtering button. The IP Filtering dialog appears. Set the appropriate filter and click Ok to close the dialog. 7. Click Ok on the VLAN Configuration screen to save changes.

10.2.1 Mapping WLANs to VLANs Use the following steps to map a VLAN, that is not already a part of any subnet, to a WLAN: 1. Select the desired WLAN from the menu. 2. From the Subnet pulldown menu select none. The WLAN is now not associated with any subnet and the VLAN field can now be edited. 3. Enter a VLAN ID in the VLAN field to map that VLAN ID to the current WLAN.

4. Click the Apply button to save the changes.

WS2000 Use Cases 12-3

12.1 Retail Use Case 12.1.1 A Retail Example 12.1.1.1 Background CCC Clothing Stores have, in the past, used POS terminals with a 10BaseT Ethernet connection to an inhouse server. Management has decided to install wireless networking in the stores. Wireless point of sale (POS) terminals and printers will allow them to be more flexible with store layout. Wireless handheld terminals for inventory and price lookup will make inventory faster and more accurate. In some stores, management is adding a cafe with free wireless Internet access. The hope is that customers will visit more often and stay longer if their partners can use the Internet while they shop. The following links show the tasks that the system administrator will carry out to complete the wireless upgrade.

12.2 The Plan Clarissa is the employee assigned to implement the new network in San Jose. She needs three very different security policies. Wireless security policies are part of a WLAN configuration, so she will need three different WLANs. • WLAN #1: Confidential information, such as credit card numbers and customer purchases, will travel over the links to wireless POS terminals. For these, she wants the strongest security measures possible. The two components of a wireless security policy are user authentication and data encryption. The corporation has a RADIUS server for user authentication and it is a logical choice for this application. If the corporation did not have a RADIUS server, an alternative would have been to install Kerberos on the in-store server and use Kerberos user authentication. As for data encryption, WEP is not secure enough for this traffic. A survey of the wireless POS terminals reveals that they all support WPA-TKIP, so Clarissa will use WPA-TKIP for data encryption. • WLAN #2: The wireless printers are difficult to misuse - no keyboards - and the data stream to them does not include any information that needs strong encryption. On this WLAN, Clarissa can limit user access by limiting connections to just those devices which have their MAC addresses entered in the switch. The data will be WEP encrypted. • WLAN #3: In the cafe, Clarissa wants an open network - no authentication or encryption. She believes that otherwise the support problems will be too difficult. But management wants to be absolutely certain that users of the cafe net cannot get access to the store computers or POS terminals. The WS2000 allows the administrator to restrict access from one subnet to another, so Clarissa will create a subnet that is just for WLAN #3, and then restrict access from that subnet to the other subnets.

12-4 WS2000 Wireless Switch System Reference Guide

This plan covers all the wireless devices—the POS terminals, the printers, and the customer laptops— except the wireless handheld terminals. Clarissa decides to put them on the WLAN with the POS terminals. There are also some conventional, 100baseT wired devices to consider. There is the store server and two wired POS terminals. Clarissa will put all of these on the 100baseT ports on the WS2000. To keep things simple, Clarissa decides to define one subnet for each WLAN and assign one Access Port to each WLAN. The wired devices will be part of the POS subnet. The WS2000 will connect to the Internet through a DSL line.

12.3 Contacting the Wireless Switch Clarissa sets up a direct network link between her laptop and the switch, plugging the cable into one of the local, non-WAN, ports. The switch defaults to having all the LAN ports on the first subnet and that subnet having an IP address of 192.168.0.1. So, as far as this connection is concerned, the switch comes up with an initial IP address of 192.168.0.1. She sets her laptop to have an IP address of 192.168.0.2 and a netmask of 255.255.255.0. She also sets the gateway IP address to be 192.168.0.1, the WS2000ws2000’s IP address.

WS2000 Use Cases 12-5

Clarissa starts her web browser and enters “http://192.168.0.1/” as the URL. The WS2000 sends a login page to her browser. She logs in using “admin” for the username and “symbol“ as the password. The system immediately asks her to change the password to something else. Clarissa does so.

12.3.1 Entering the Basic System Settings Clarissa selects System Settings from the left menu, located under the System Configuration heading. Upon selecting this screen for the first time, the WS2000 switch immediately asks her to chose a country. Different countries have different regulations for the use of these radio frequencies. Setting the location configures the switch to use only the channels, frequencies, and power levels that are legal for that country. She sets the country to United States - US. The system name is used to distinguish between WS2000 switches for remote configuration. She gives the switch a descriptive name, “SanJose-1”. This name will appear in the footer for subsequent configuration windows for the switch. She does not need the name now, while she is in San Jose. But later, when she returns to corporate headquarters and wants to log into several switches remotely, it will help her to know which switch she is working on. She also enters a slightly longer description on the System Location field. She enters her E-mail address into the Admin Email Address box. CCC uses an SNMP manager that has the capability of monitoring network devices and sending email to the manager of a device that is in an unusual state. This is the email address that will be supplied to that SNMP manager for this switch. Clarissa clicks the Apply button to save her changes.

12-6 WS2000 Wireless Switch System Reference Guide

12.3.2 Setting Access Control In the WS2000 Access screen, Clarissa controls which network interfaces can be used to reconfigure the WS2000 switch. She is currently using HTTP access on port 80 over the LAN, so she leaves that on. She may also want to make changes using the Command Line Interface (CLI), so she leaves on local CLI access. She wants to be able to manage the switch from corporate headquarters, but she does not want to leave the standard HTTP port, port 80, open over the WAN. She elects to leave port 443 open over the WAN instead. She knows she will want to monitor the switch from her SNMP system at corporate, so she leaves SNMP WAN access on. AirBEAM is a Motorola Technology software system designed to simplify maintenance of wireless devices. CCC Clothing Stores recently purchased an AirBEAM license as part of a major commitment to Motorola Technology wireless bar code scanners for inventory. Clarissa would like to integrate the WS2000 into the AirBEAM management system and she leaves AirBEAM access on.

WS2000 Use Cases 12-7

Clarissa clicks the Apply button to save her changes. Clarissa leaves the rest of the System Configuration screens for now, moves to the left menu, and clicks on Network Configuration so that she can begin to define the subnets.

12.3.3 The IP Address Plan Subnets can be renamed, assigned an IP address, and have ports associated with them. Clarissa needs to plan how she is going to assign IP addresses to the subnets and the devices on them. Clarissa only has one IP address from corporate for this store. She will use network address translation (NAT) for all of the devices, making request from those devices look to the outside world as if they came from the single static IP address that she has. For the devices, she plans to use IP numbers from the range 192.168.*.*, because IP addresses in that range are designated for internal use only. She will assign them as follows: Subnet

IP Address Range

192.168.0.***

POS subnet

192.168.1.***

Printer subnet

192.168.2.***

Cafe subnet

And for each subnet: 192.168.**.1

The WS2000 address on that subnet

192.168.**.2 to 192.168.**.10

Devices with static IP addresses

192.168.**.11 to 192.168.**.254

Devices with DHCP-supplied IP addresses

WIth this plan, she can begin to configure the individual subnets.

12-8 WS2000 Wireless Switch System Reference Guide

12.4 Configuring POS Subnet Clarissa selects the first subnet from the LAN menu items in the left menu. Clarissa renames this subnet “POSsn”, then gives the switch an IP address of 192.168.0.1 on that subnet and assigns a subnet mask of 255.255.255.0. The devices on this subnet are: • Everything on the POS WLAN: wireless POS terminals and wireless handheld terminals • One wired POS terminal on port 4 and one on port 5 • One in-store server on port 6 Using the Interfaces section of the screen on the right, she associates the first WLAN with this subnet, as well as Ports 1 (the one the POS WLAN is plugged into), 4 and 5 (the wired POS terminals), and 6 (the server). She activates the DHCP server and gives it an IP address range of 192.168.0.11 to 192.168.0.254.

After the Address Assignment Range is entered, Clarissa clicks Advanced DHCP Server.

WS2000 Use Cases 12-9

The Default Gateway is already set to the subnet address. This is the IP address to which the DHCP clients on this subnet will forward their outbound traffic. Clarissa fills in the DNS Server addresses, which corporate has specified. This will also be supplied to the DHCP clients. The DHCP Lease Time is the time an IP address will remain assigned to a client after there is no more activity. She leave it at the default and clicks Ok to save her changes. Then, in the subnet screen, she clicks Apply to save her overall changes. Now she will configure the printer subnet.

12.5 Configuring the Printer Subnet Clarissa selects the second subnet from the list of LAN menu items in the left menu. She renames this subnet â&#x20AC;&#x153;Printsnâ&#x20AC;?, then gives it an IP address of 192.168.1.1 and a subnet mask of 255.255.255.0. The only devices on this subnet are the wireless printers. Using the Interfaces section of the screen, she associates the second WLAN with this subnet. She activates the DHCP server with an IP address range of 192.168.1.11 to 192.168.1.254.

12-10 WS2000 Wireless Switch System Reference Guide

After the Address Assignment Range is entered, Clarissa clicks Advanced DHCP Server.

Clarissa enters the DNS server IP addresses and leaves the Default Gateway and DHCP Lease Time at their defaults. She clicks Ok in the Advanced DHCP Server window and then Apply in the Subnet window to save her changes. Now Clarissa will configure the Cafe subnet.

WS2000 Use Cases 12-11

12.6 Configuring the Cafe Subnet Clarissa selects the third subnet in the LAN menu list under Network Configuration in the left menu. She then renames this subnet “Cafesn“and gives it the IP address 192.168.2.1 and a subnet mask of 255.255.255.0. The only devices on this subnet are the customer’s laptops in the cafe. Using the Interfaces section of the screen, she associates the third WLAN with this subnet, and activates the DHCP server with an IP address range of 192.168.2.11 to 192.168.2.254.

Clarissa clicks Advanced DHCP Server and enters the DNS server IP addresses. The Default Gateway is fine. However, Clarissa expects the cafe patrons to come and go frequently, so she reduces the IP address lease time to 1800 seconds. This means that a DHCP client mobile unit will give up its IP address if it is inactive on the network for more than half an hour. This seems about right for the usage patterns that she expects for the cafe. If she gets complaints, she will increase it to an hour.

12-12 WS2000 Wireless Switch System Reference Guide

Clarissa clicks the Ok button in the Advanced DHCP Server window, then on the Apply button in the subnet screen to save her choices. The subnets are now configured. Next Clarissa configures the WAN interface.

12.7 Configuring the WAN Interface Now Clarissa selects the WAN node in the left menu. Here she enters the static IP address assigned to this store by CCC corporate. She also enters the other information supplied to her by corporate: the gateway IP address, the subnet mask, and the DNS server IP addresses. She is connecting by a DSL modem, but because she has a static IP address, her Internet service provider (ISP) does not require PPP-over-Ethernet connection information. If her ISP required PPPoE account information, she would have to enter that information in the PPP-over-Ethernet section of the screen.

WS2000 Use Cases 12-13

If corporate had not paid their ISP for a static IP address for each store, she would have selected the This interface is a DHCP Client option and the WAN configuration settings would have been assigned by the ISP each time they connected to the Internet. Clarissa clicks the Apply button to save her changes.

12.8 Configuring Network Address Translation (NAT) Clarissa has only one public IP address for the whole store. She will use network address translation to make all requests from internal IP addresses to appear as if they came from the single public IP address. She selects the NAT node under the WAN item in the left menu. The screen shows all IP addresses assigned to the switch in the WAN interface configuration step. In this case, there is one IP address shown. She selects â&#x20AC;&#x153;1 to Manyâ&#x20AC;? from the NAT Type menu to the right of the IP address.

12-14 WS2000 Wireless Switch System Reference Guide

After she makes this selection a new button appears, labelled “1 to Many Mappings”. She selects the “1 to Many Mappings“ button.

If Clarissa had more than one static IP address, she would have been able to assign several to the WAN interface. This screen would be used to choose how the internal IP addresses on each subnet translated into the selection of external IP addresses. However, she has only one external IP address. All requests from any IP address on the store network will be translated into a request using the single public IP address for the store. Clarissa clicks the Ok button to confirm the mappings and then clicks the Apply button in the main screen to confirm the NAT choices and save her choices on the switch.

12.9 Inspecting the Firewall Clarissa selects the Firewall item in the left menu. Each of the check box items represents a type of attack which the WS2000 can filter out. She checks to see that all of the options are enabled.

WS2000 Use Cases 12-15

Clarissa clicks the Apply button to confirm that all attacks listed will be filtered.

12.10 Configuring the Access Ports So far, Clarissa has been operating with the WS2000 connected only to her laptop. To configure the Access Ports, she will need to connect them to the switch. She plans to use switch ports as follows: Switch Port

Connected to

Port 1

Access port for the POS WLAN

Port 2

Access port for the Printer WLAN

Port 3

Access port for the Cafe WLAN

Port 4

Wired POS terminal #1

Port 5

Wired POS terminal #1

Port 6

In-store server

12.10.1 Setting Access Port Defaults The WS2000 allows the user to specify the default settings for Access Ports. Clarissa expands the Access Ports node in the left menu and selects the 802.11b Defaults node. Clarissa has only 802.11b Access Ports. All of the Access Ports will be indoors, so she specifies Placement as Indoors. She sets the Channel to one, though she will reset each Access Port to a different 802.11b channel later. She sets the Power Level to 20dB, the maximum level allowed in the US.

12-16 WS2000 Wireless Switch System Reference Guide

She does not change the supported ratesâ&#x20AC;&#x201D;using the Set Rates buttonâ&#x20AC;&#x201D;but leaves them as they are. The switch will operate at the maximum rate allowed by radio conditions, scaling back as needed. She also does not change the Antenna Diversity setting, Short Preamble setting, RTS Threshold, or the Beacon Settings. These parameters control some of the broadcast mechanics of an 802.11 conversation between mobile units and Access Ports. In most cases, there is no reason to change them.

Clarissa clicks Apply to save her changes. After setting the default settings for 802.11a and 802.11b Access Ports, Clarissa removes the Access Ports from their packaging and labels the each with the name of the WLAN which it will support. She connects the Access Ports to the switch, using the ports selected in her plan.

WS2000 Use Cases 12-17

12.10.2 Naming the POS Access Port Having specified the general Access Port defaults, Clarissa goes on to name and configure the Access Port for the POS WLAN. She selects the first Access Port in the left menu.

In the Properties section, Clarissa enters a new name for the Access Port and a brief description of its permanent location. In the Radio Settings section, Clarissa sets the Channel to 3. She knows that the store uses cordless phones that transmit on channel 1. She also wants to maintain some separation between the channel used by this Access Port and the other Access Ports at this location. She doesn’t change any of the other settings. She clicks the Apply button to save her changes.

12.10.3 Configuring the Printer Access Port Clarissa configures the Printer Access Port in a similar way. She give it the name “Printer AP“and a location description. She assigns channel 6 to this Access Port, avoiding contention with the POS AP and the Cafe AP.

12-18 WS2000 Wireless Switch System Reference Guide

She clicks the Apply button to save her changes.

12.10.4 Configuring the Cafe Access Port Finally, she names the third Access Port â&#x20AC;&#x153;Cafe APâ&#x20AC;? and gives it a channel of 9. In this case she makes sure Support Short Preamble is not selected. There are two preambles in use in the wireless world, an older, longer one and a newer, shorter one. Most wireless devices support both and use the shorter one by default. However, in the cafe, there will be older wireless devices coming in and rather than confuse them, she will stick with the longer preamble on this WLAN.

Again, she clicks the Apply button to save her changes.

WS2000 Use Cases 12-19

12.10.5 Associating the Access Ports to the WLANs Now Clarissa selects the APs/Radio item in the left menu. This screen indicates which Access Ports are associated with which WLANs. First Clarissa looks in the [Network Configuration] --> Wireless screen to determine that all three WLANs are enabled. In the Radio Adoption Table screen, the screen begins with a single line with “ANY” as the Start MAC address, “ANY” as the End MAC address, and checks under all three of the WLANs. Clarissa removes the checks from the WLAN check boxes. Any discovered radio is displayed in the Radio Adoption Table. Clarissa looks in the table to determine that the required radios are discovered. By default, all the radios are checked for all WLANs. This indicates that all radios can be adopted by all WLANs. Clarissa removes the checks for all the radios for all WLANs. Clarissa then checks the appropriate radio for each WLAN.

Clarissa clicks the Apply button to save her choices.

12.11 Configuring the Cafe WLAN Clarissa clicks the button to the left of the Wireless menu item in the left menu. It opens up to show the individual WLANs. She selects the third WLAN. This is the WLAN which she plans to use for the cafe WLAN. The WLAN name is used with in the WS2000 configuration screens to make the interface easier to navigate. She names this WLAN from “WLAN3” to “Cafe”. She also gives it an ESSID of “CCC-Cafe”. The ESSID is broadcast to the users and will be what the cafe users see when they select a wireless network on their laptops. Finally, she uses the Subnet pull-down menu to make this WLAN part of the third subnet, the “Cafesn” subnet. She leaves the Disallow MU to MU communications option unchecked. She is certain that some cafe users will want to communicate between themselves, so she does not choose the Disallow. She turns on Answer Broadcast ESS for this WLAN. Some mobile units come with a default ESSID of “101”. This option allows the WLAN to respond to these mobile units even if the WLAN is set up with a

12-20 WS2000 Wireless Switch System Reference Guide

different ESSID. Since the cafe is a public access WLAN, leaving this option on will make it easier for the cafe customer to associate with the WLAN. For the private WLANs on this switch, she will turn this option off.

She clicks the Apply button to save her choices.

WS2000 Use Cases 12-21

Clarissa goes to the left menu and clicks the button to the left of the Cafe WLAN node. A menu item labeled “Cafe Security” is displayed and Clarissa selects it. She confirms that the Cafe Security screen shows that no authentication and no encryption methods.

Clarissa clicks the Apply button to save her choices.

12.12 Configuring the Printer WLAN For the printer WLAN, Clarissa makes the following selections: Name

Printer

ESSID

CCC-Printer

Subnet

Printsn

Disallow MU to MU Communication

Yes

Secure Beacon

Answer Broadcast ESS

The wireless printers will never need to communicate with each other directly. MU-to-MU communications can be safely disallowed. Allowing “Answer Broadcast ESS” is a way to allow mobile units that are not configured with the network ESSID to associate with the WLAN. She knows that she will configure all of the mobile units on this WLAN with the correct ESSID, so she disallows this option, potentially keeping a cafe customer out of the printer WLAN.

12-22 WS2000 Wireless Switch System Reference Guide

Clarissa clicks the Apply button to confirm her choices.

WS2000 Use Cases 12-23

Clarissa clicks the + to the left of the Printer WLAN menu item and selects the Printer Security item. In the screen that displays, Clarissa selects no authentication. She enters the MAC numbers of the wireless printers in the Mobile Access Control section. The MAC numbers are unique numbers assigned to every network-cable hardware device and are usually listed on the same label that shows the device’s model number and serial number. She enters each by clicking on the Add button and entering the MAC address in the Start MAC column of the new row.

She uses the Mobile Unit Access Control pull-down menu to select Deny. This specifies that the switch will deny access to any mobile unit that has a MAC address that is not listed. In the Encryption Methods section, she selects WEP 128 (104-bit key). WEP encryption is weak compared with WPA-TKIP, but still requires a day or so of solid traffic samples and a fair amount of effort to break. There is no data transversing this link that a data thief couldn’t find in the trash. In any case, the store’s wireless printers only support WEP. She clicks the WEP Key Settings button and enters the keys she will use:

12-24 WS2000 Wireless Switch System Reference Guide

She clicks the Ok button to confirm the WEP key selections, then the Apply button to confirm the screen selections.

12.13 Configuring the POS WLAN For the POS WLAN, she makes the following choices: Name

POS

ESSID

CCC-POS

Subnet

POSsn

Disallow MU to MU Communication

Secure Beacons

Answer Broadcast ESS

Allowing “Answer Broadcast ESS” is a way to allow mobile units which are not configured with the network ESSID to associate with the WLAN. She knows that she will configure all of the mobile units on this WLAN with the correct ESSID, so she disallows this option, potentially keeping a cafe customer out of the POS WLAN.

Clarissa clicks the Apply button to save her choices.

WS2000 Use Cases 12-25

Clarissa then clicks the “+” to the left of the POS WLAN in the left menu and selects POS Security. In that screen, she selects 802.1x EAP for authentication. This will allow her to use the corporate RADIUS server for user authentication. Under Encryption Methods, she selects WPA/WPA2-TKIP encryption.

Then she selects the “802.1x EAP Configuration” key. In the next screen, she enters the corporate RADIUS server’s IP address, its port number, and the secret string needed to access it. In this case, her corporation is using a port number other than the standard one of 1812. She wants to allow the software to reauthenticate the users, but she is uncomfortable with the 3600 second (one hour) interval, and changes it to 10 minutes (600 seconds). She sees no reason to change the other 802.1x parameters.

12-26 WS2000 Wireless Switch System Reference Guide

She clicks the Ok button in the 802.1x-EAP configuration window. She then clicks the WPA-TKIP Settings button in the security screen. Clarissa selects the Use WPA choice to enable WPA. WPA is disabled by default. TKIP encryption protocol calls for keys between two specific nodes to change with every packet. However, there is no standard with respect to how often one should change keys for broadcast packets. A very busy network with lots of broadcast packets could generate enough packets for successful decrypting in about an hour. Clarissa sets the system to rotate the broadcast keys every five minutes. TKIP requires an initial shared key to start, so that all messages can be encrypted, including the first one. This initial key setting would be entered in the lower half of this screen, if it were needed. However, if 802.1x EAP user authentication is enabled, the authentication server will provide the initial key to the client and the key settings will be grayed out. In this case, Clarissa is using 802.1x EAP user authentication, so she does not have it enter an initial shared key.

WS2000 Use Cases 12-27

With this, Clarissa has finished configuring the basic WLAN configuration and the WLAN security. She clicks the Ok button in the WPA-TKIP window and then the Apply button in the WLAN security screen.

12.14 Configuring Subnet Access Clarissa wants the two internal subnets to have complete access to one another, but she wants the Cafe subnet to have access only to the WAN. In the left menu, she opens the Firewall item under Network Configuration and selects the Subnet Access node.

12-28 WS2000 Wireless Switch System Reference Guide

To set the subnet access for a pair of subnets, she clicks the square for traffic from one subnet to another and then uses the detail section, which appears below, to determine the rules for traffic between those two subnets. She allows the Cafe subnet to have full access to the WAN. For the Cafe subnet to or from any other internal subnet, she selects the appropriate square, then uses to the detail box below to “Deny” all protocols.

For the POS subnet and the Printer subnet, she selects “Allow” all protocols when going to the WAN, the POS subnet, and the Printer subnet.

After specifying all of the subnet access rules, she clicks the Apply button to save her changes.

WS2000 Use Cases 12-29

12.15 Configuring the Clients Clarissa has now finished configuring the switch. Next she configures the wired clients. Going to each device, she gives it the IP address and other networking information that it will need to communicate with the switch: Client

IP Address

Subnet Mask

Gateway

WS2000 Port

Wired POS terminal #1

192.168.0.4

255.255.255.0

192.168.0.1

Wired POS terminal #2

192.168.0.5

255.255.255.0

192.168.0.1

Server

192.168.0.6

255.255.255.0

192.168.0.1

Then she does the same thing with the wireless clients: Client type

WLAN ESSID

Wireless channel

Authentication

Wireless POS terminals

CCC-POS

802.1x EAP

WPA-TKIP

Handheld terminals

CCC-POS

802.1x EAP

WPA-TKIP

Wireless printers

CCC-Printers

None

WEP

The remaining tasks are to test the network and to put the Access Ports in their permanent locations.

12.15.1 Testing Connections Clarissa powers up several sample devices and tests them, to be sure that they work as configured. She tests whether the devices can connect to the wireless switch and whether they can connect to devices on other subnets. After she is confident that everything is working, she moves the Access Ports to their permanent locations. She connects the WS2000 to the DSL modem. Finally, she tests the connection from each subnet to the WAN. The store network is now complete.

12-30 WS2000 Wireless Switch System Reference Guide

12.16 Field Office Use Case 12.16.1 A Field Office Example 12.16.1.1 Background Leo is the network administrator, system administrator, and IT professional for a field office with 60 employees. The users include sales people, sales engineers, office administration and customer support people. All of the sales personnel have laptops and many of them have personal digital assistants (PDAs). The office is connected to the Internet and to corporate through a frame relay link. Between the office network and the frame relay, there is a router and a virtual private network (VPN) appliance. All traffic to corporate is encrypted by the VPN appliance. Traffic to other addresses passes straight through. Leo installed a wireless access point about six months ago and quickly found that many employees preferred to use it. However, the throughput of the lone unit was not enough to service 40 or so users and coverage was weak in many areas of the building. In addition, Leo was doing user authentication by maintaining a list of permissible user MAC addresses on the access point. This required modifications to the list once or twice a week. Recently, when a laptop was stolen, Leo could not determine which MAC address to remove from the list for several hours. He concluded that a better method of user authentication was needed. Also, the data encryption on the old access point was WEP and WEP encryption can be broken with several hours of data encrypted with the same key. Leo changes the key every week, but some users complain when last week’s key does not work anymore. Leo has decided to upgrade to a WS2000 wireless switch. He will have four Access Ports, one in the administration office area, one in the sales office area, one in the sales engineering area, and one in the engineers’ demonstration room. Throughput and coverage will increase significantly. Leo will convert to 802.1x/EAP-TTLS user authentication through the corporate RADIUS server and convert to WPA2 encryption, improving security considerably and reducing maintenance significantly. Leo’s company is also growing. Corporate has rented an expansion office for engineering in another part of the same building. Leo needs to establish secure communication from the engineering subnet to this expansion office. The other office will also have a WS2000, so Leo will establish a direct VPN link to that WS2000 and use the VPN as the secure communication link. The following links show the tasks that Leo will carry out to complete the wireless upgrade.

12.17 The Plan Each WS2000 WLAN has exactly one security policy, where a security policy is defined as a user authentication method and a data encryption method. Because each WLAN can have one and only one security policy, WLAN configuration is usually defined by the security needs of the installation. If two groups of users require different security policies, then they must associate to the WS2000 through different WLANs. See the retail case study for an example of an installation where different security needs drive the need for separate WLANs. In this situation, all of Leo’s users will use the same security system: 802.1x/EAP-TTLS user authentication and WPA data encryption. Leo can set up the WLANs in any way that is convenient. Corporate has given Leo three static IP addresses for the wireless network. He will configure the WS2000 as a DHCP server giving out internal-use-only IP addresses and use network address translation (NAT) in the switch to convert the outward-bound traffic to one of the static IP addresses.

WS2000 Use Cases 12-31

To keep things simple, he will define one subnet for the administration users, one subnet for the sales and marketing users, and one subnet for the engineers. Each subnet will have one WLAN associated with it and one Access Port. The only exception is the engineering subnet, which will have one WLAN and two Access Ports. The marketing subnet will not have any access to the engineering or administration subnets. All of the subnets will be restricted to just HTTP, SMTP, and POP access to the WAN.

12.18 Configuring the System Settings 12.18.1 Contacting the Wireless Switch To begin configuration of the switch, Leo sets up a communication link to the switch. Leo starts with a direct network link between his laptop and the switch, plugging the cable into one of the local, non-WAN, ports. The switch defaults to having all the LAN ports on the first subnet and that subnet having an IP address of 192.168.0.1. So, as far as this connection is concerned, the switch comes up with an initial IP address of

12-32 WS2000 Wireless Switch System Reference Guide

192.168.0.1. He sets his laptop to have an IP address of 192.168.0.2 and a netmask of 255.255.255.0. He also sets the gateway IP address to be 192.168.0.1, the WS2000’s IP address.

Leo launches his web browser and enters “http://192.168.0.1/” as the URL. He logs in using admin for the username and symbol as the password.

WS2000 Use Cases 12-33

As soon as he logs in, the WS2000 asks him to set the password. He sets the administration password to something relatively secure.

He presses Update Password Now to record his changed password.

12.18.2 Entering the Basic System Settings The interface opens by displaying the System Setting screen. This screen is also accessible by clicking the toggle to the left of System Configuration in the left menu, then selecting System Settings in the left menu. The first time System Settings are displayed, a dialog box is displayed, warning the administrator to select a country of operation.

Different countries have different regulations for the use of radio frequencies. Setting the location configures the switch to use only the channels, frequencies, and power levels that are legal for that country. Leo sets the location to United States - us. The system name is used to distinguish between WS2000 switches for remote configuration. Leo gives the switch a descriptive name, Atlanta1. This name will appear in the footer for subsequent configuration windows for the switch. He does not need the descriptive name, but he wants to put in something appropriate in case he needs it later. If the office eventually has more than one wireless switch, the name will help him to know which switch he is working on. He also enters his email address into the Admin Email Address box. Leoâ&#x20AC;&#x2122;s corporation uses an SNMP manager which has the capability of monitoring network devices and sending email to the manager of a device that is in an unusual state. This is the email address that will be supplied to that SNMP manager for this switch.

12-34 WS2000 Wireless Switch System Reference Guide

12.18.3 Setting Access Control Leo then clicks the WS 2000 Access node in the left menu. This controls which subnet can be used to reconfigure the WS2000 switch and how that reconfiguration can be accomplished. Leo will be inside the LAN, so he leaves on all means of reconfiguring from within the LAN by selecting the From Any-nw check box. Corporate may want to have read access from outside the LAN, so Leo leaves on SNMP access from the WAN. AirBEAMÂŽ is a Motorola Technology product for the management of software on wireless devices. Leo does not have a copy of AirBEAM yet, but he hopes to get one when the company purchases some Voice over IP (VoIP) phones. He also doesnâ&#x20AC;&#x2122;t expect to access the switch from the Compact Flash card slot. So, he turns AirBEAM Access off.

WS2000 Use Cases 12-35

Leo clicks on the Apply button in the WS2000 Access screen to save his changes.

12.19 Configuring the LAN Leo clicks the toggle to the left of Network Configuration in the left menu. The tree expands and he selects the LAN item.

12-36 WS2000 Wireless Switch System Reference Guide

This screen shows the subnets, their IP addresses, and the network interfaces (the 10/100BaseT ports and the WLANs) that are currently associated with each subnet. Only the first subnet is initially enabled, so Leo clicks on the check boxes to the left of Subnet2 and Subnet3 to enable them. He clicks the Apply button to record his changes. Next Leo needs to configure each of the subnets. He clicks the toggle symbol to the left of LAN in the left menu to expand it.

12.19.1 Configuring the Engineering LAN Leo selects Subnet1 from the choices under the LAN heading. He enters a new name for the subnet, EngSN, to make it easier to recognize this subnet throughout the WS2000 interface.

WS2000 Use Cases 12-37

He also selects the option This interface is a DHCP Server. Choosing this DHCP option means that the switch will pick IP addresses from the Address Assignment Range and assign them to network clients on this subnet, as needed. This screen also sets the IP address for the switch’s interface to the subnet. Any address that starts with “192.168” is an internal-use-only IP address. That is, network administrators are free to use these IP addresses anyway they want, as long as the IP addresses are never visible to the outside world. The switch defaults to an address of 192.168.0.1 for the first subnet interface. Leo elects to use the range of IP addresses from 192.168.0.11 to 192.168.0.254 for the DHCP clients in this subnet. Leo then selects the Advanced DHCP Server button. The DNS server IP addresses and the Gateway IP address entered here will be passed down the DHCP clients for this subnet for their own use while associated with this subnet. Leo enters the IP addresses that the corporation’s IT department has specified for the corporate primary and secondary DNS servers. For the gateway, Leo enters the IP address for the subnet, the same IP address that he entered for the IP Address in the IP Parameters section of the Subnet screen. The DHCP Lease Time (sec) specifies how long in seconds a client may keep an IP address when that client is not active on the net. The lease time is currently set for 86,400 seconds, or 24 hours. Leo expects that people using these WLANs will connect for a work day or not. While in the office, he expects that their machines will initiate contact with the network every 10 or 15 minutes for email. When they unplug to go home, this lease time will hold their IP address for another full day and not return it to the usable pool until the end of the next day. Leo would prefer that the lease time expire sometime during the night. He figures a lease time of somewhere between 10,000 seconds and 30,000 seconds is appropriate for this application. Leo sets it to 10000 seconds and figures he will change it if anyone complains. The WINS Server field is designed to supply the Windows Network Server IP address to any DHCP clients that request it. Leo supplies the IP number for the local WINS server.

12-38 WS2000 Wireless Switch System Reference Guide

The Domain Name field will be supplied to any DHCP clients that request it. Leo enters his companyâ&#x20AC;&#x2122;s domain name.

There is no reason to set up static DHCP mappings now. These would permanently lease an IP address to a client with a specific MAC address. Leo clicks the Ok button on the Advanced DHCP Server window, then the Apply button on the subnet window.

12.19.2 Configuring the Sales Subnet The sales and marketing subnet is configured exactly the same way as the engineering subnet, though with a different name and a different IP address range.

WS2000 Use Cases 12-39

Leo selects the Advanced DHCP Server button and follows the same procedures as he did for the engineering subnet. Leo clicks the Ok button on the Advanced DHCP Server window, then the Apply button on the subnet window. The administration subnet is configured in the same way:

12-40 WS2000 Wireless Switch System Reference Guide

Again, Leo fills out the advanced DHCP screen as he did for the two previous subnets. Leo clicks the Ok button on the Advanced DHCP Server window, then the Apply button on the subnet window. The next step is to configure the WAN interface.

12.20 Configuring the WAN Interface Next Leo configures the WS2000 WAN interface. This interface connects the WS2000 switch to the VPN appliance and, through that appliance, to the Internet. Leo enables the WAN interface, but leaves the DHCP Client option disabled. Instead of using DHCP to get address information for the switch, he enters the permanent information which he previously obtained from the corporate network administrator. He enters the IP address for the switch, the gateway address (in this case, the VPN appliance), and the IP addresses of the corporate primary and secondary DNS servers. The corporation has a frame relay link between this office, the corporate network and the Internet. If the connection to the WAN had been through a DSL link, the account information would be entered in the PPP over Ethernet section on the bottom of this screen. Since it will not be needed, Leo makes sure that the Enable check box in the PPP Over Ethernet section is not checked.

Leo has three addresses for this switch. He plans to use one address for the traffic from each of the subnets. He clicks the More IP Addresses button and enters the other two IP addresses:

WS2000 Use Cases 12-41

He clicks Ok button in the address window, then the Apply button on the WAN window to save his changes. The next step is to set up the network address translations (NAT).

12.21 Configuring the WAN Interface 12.21.1 Setting Up Network Address Translation After entering the IP addresses for the WAN interface, Leo clicks the toggle to the left of the WAN item in the left menu to expand it. He then selects the NAT item. The WS2000 displays the three IP addresses he entered when configuring the WAN.

Each of these IP addresses will serve as the alias for all of the traffic from its corresponding subnet. That is, each IP address will serve as the only alias for many internal-only IP addresses. Leo chooses 1 to Many in

12-42 WS2000 Wireless Switch System Reference Guide

the pull-down menus to the right of each IP number. As he does so, a 1 to Many Mappings button appears to the right of the pull-down menus, in the Outbound Mappings column.

Leo clicks any of the NAT Ranges button to the right of the IP addresses. The 1 to Many Outbound Mappings window displays. Leo uses the pull-down menu to set the outbound IP address for each subnet. These are the same as the inbound IP addresses that he specified in the WAN configuration screen.

He clicks the Ok button to save his entries, then clicks the Apply button in the NAT screen. The next step is to configure the firewall.

12.22 Confirm Firewall Configuration After setting the NAT ranges, Leo selects Firewall under WAN in the left menu. The WS2000 displays a series of Configurable Firewall Filters, all of which are currently enabled.

WS2000 Use Cases 12-43

Leo examines the list and sees no reason to turn off any of the filters. He clicks the Apply button. The next step is to determine which Access Ports each WLAN will use.

12.23 Adopting Access Ports Now that the LAN and WAN interfaces are configured, Leo needs to specify which Access Ports will go with which wireless LANs (WLANs). To do this, Leo needs the MAC address for each Access Port. He removes them from their packaging and connects them to the switch. The WS2000 discovers the connected APs automatically. Leo finds that they have consecutive MAC addresses: 00:A0:F8:BB:FC:94 through 00:A0:F8:BB:FC:97. He decides that he will deploy them as follows: MAC Address

Location

WLAN3

He marks each Access Port with its intended location and WLAN, so he will not get confused later. Leo selects the Wireless item in the left menu. He sees that only the first wireless LAN is enabled. None of the WLANs have the names he would like them to have. He clicks on the check boxes to the left of WLAN2 and WLAN3, then on the Apply button to enable these two WLANs.

12-44 WS2000 Wireless Switch System Reference Guide

Now that the WLANs are enabled, Leo needs to specify which Access Ports go with which WLANs. He selects APs/Radio from the menu tree on the left. All discovered APs are listed in this screen.

He deselects the check boxes to the right of the row in which the MAC address range is specified as ANY.

WS2000 Use Cases 12-45

For the engineering WLAN, Leo selects the AP with MAC of 00:A0:F8:BB:FC:94 and makes sure that all WLAN check boxes are not checked. He then selects the WLAN1 check box for this AP. He performs the same actions for the AP with MAC of 00:A0:F8:BB:FC:95. For the Marketing WLAN, Leo selects the AP with MAC of 00:A0:F8:BB:FC:96. He makes sure that only the check box under the WLAN2 column is selected for this AP. For the Marketing WLAN, Leo selects the AP with MAC of 00:A0:F8:BB:FC:97. He makes sure that only the check box under the WLAN3 column is selected for this AP.

Leo clicks the Apply button to save his changes. The next step is configure the WLANs.

12.24 Configuring the WLANs Leo has specified which Access Ports go with which wireless LANs (WLANs). Now, he needs to name and configure each WLAN. He expands the Wireless node in the left menu, and selects the first WLAN listed. Leo gives the WLAN the name EngWLAN so that subsequent screens in the WS2000 interface will be a little easier to read. The ESSID is the identification string that his users will see, so he uses a name that will be easy for them to recognize, the string Engineering. The interface shows that this WLAN is already part of the Engineering subnet, so there is no reason to change it.

12-46 WS2000 Wireless Switch System Reference Guide

In the Advanced section of the screen, the Disallow MU to MU Communications setting would keep mobile units from communicating directly with each other. Leo believes that people sometimes share files directly, laptop to laptop, instead of using the file server. Leo does not want to prevent this type of communication, so he leaves this option disabled. Answer Broadcast ESS instructs the Access Ports on this WLAN to respond to communications from mobile units that do not know what the ESSID for the wireless network is and which are using a default ESSID of 101. Leo knows that there are no such units in the office; if there were they would not have worked with the previous access point. Leo leaves this check box unchecked. The Secure Beacon option prevents the APs from broadcasting the ESSID in its beacons. Leo turns on this option to further secure his corporate network. Leo clicks the Apply button to save his changes.

12.24.1 Security The next step to set security for the engineering WLAN. He selects the toggle to the left of EngWLAN in the left menu to display the EngWLAN Security item. Leo selects that item and the security screen is displayed. Leo selects 802.1x EAP as the authentication method and WPA2-CCMP as the encryption method.

WS2000 Use Cases 12-47

Leo also needs to configure the 802.1x EAP system and the WPA2 encryption. Leo clicks 802.1x EAP Configuration. In the window that appears, he enters the RADIUS server information that he obtained from corporate system administration: the IP addresses of the RADIUS servers, the ports used for RADIUS communication, and the secret string used to start communication. He leaves the rest of the parameters at their default settings.

12-48 WS2000 Wireless Switch System Reference Guide

Leo clicks the Ok button to save the 802.1x EAP settings. Leo then clicks the WPA2-CCMP Settings button. WPA2 constantly changes keys, but requires an initial key, known to both ends of the communication. If Leo was not using 802.1X EAP user authentication, that initial key would need to be entered here, in the Key Settings section. However, with 802.1x EAP, the RADIUS server supplies the initial key, so that Key Settings section is grayed out for Leo. Leo does need to set the frequency with which the key for broadcast communication is changed. By default, the WS2000 changes the broadcast every 84,600 seconds, i.e., every twenty-four hours. Breaking WEP encryption requires several hours of solid traffic, so Leo decides to change the broadcast key rotation to 3600 seconds, or once an hour.

WS2000 Use Cases 12-49

Leo also selects Allow WPA/WPA2-TKIP clients in the section labelled WPA2-CCMP Mixed Mode. WPATKIP is an earlier version of the WPA encryption method. WPA2 is more secure, but not all wireless clients in Leoâ&#x20AC;&#x2122;s office are WPA2-capable. Selecting this option allows the older clients to use WPA-TKIP when they are not WPA2-CCMP-capable. Leo also selects Pre-Authentication and Opportunistic Key Caching in the Fast Roaming section. These are options that are designed to make it easier for 802.1x wireless clients to roam within a WLAN. Under Pre-Authentication, a wireless client connected to one Access Port can communicate with other Access Ports and begin the authentication procedure before beginning to actual use that Access Port for network traffic. Under Opportunistic Key Caching, a wireless client which has agreed upon a given Pairwise Master Key (PMK) with one Access Port on a given WS2000 is allowed to use that same PMK with other Access Ports connected to the same WS2000. Both options increase the speed of roaming under 802.1x security and Leo enables both of them. Leo clicks the Ok button to save his WPA2-CCMP settings, then the Apply button to confirm the WLAN configuration. This completes configuration of the engineering WLAN. The sales and marketing WLAN and the administration WLAN are configured exactly the same way, with the sole exception that they take different names and ESSIDs. WLAN

WS2000 Name

ESSID

Sales and Marketing

After these WLANs are configured, the next step is to configure the Access Ports.

12.25 Configuring the Access Ports The WS2000 allows the user to specify default settings for Access Ports. Leo expands the APs/Radios node in the left menu and selects the 802.11b Defaults node. Leo has four AP200 ports and he will be able to set the defaults for these in this section.

12-50 WS2000 Wireless Switch System Reference Guide

All the Access Ports will be indoors, so he specifies Placement as Indoors. He sets the default Channel as 1, even though all of his Access Ports will be using different 802.11b channels. He sets the Power Level to 20dBm. This will broadcast at 100 mW, the maximum level allowed in the US. He does not change the settings for Antenna Diversity, Support Short Preamble, RTS Threshold, or Beacon Settings. These parameters control some of the broadcast mechanics of an 802.11 communication between mobile units and Access Ports. In most cases, there is no reason to change them. He clicks Apply to save his choices.

After configuring the default Access Port settings, Leo gets four short 100baseT cables and connects the four Access Ports to the switch. Just to make it easier to remember which port is which, he connects the one with the lowest MAC address to the first port number, the next lowest MAC address to the next port, and so on. As he configures each Access Port, he will need to assign each Access Port to a channel. He can minimize radio interference if he has the radio channels for the different Access Ports separated as much as possible. He decides to use the following allocation: Access Port

Channel

Engineering Offices

Demo Room

Sales and Marketing

Administration

He clicks the toggle to the left of Access Ports in the left menu and selects the menu item labeled AP1. The WS2000 has found and queried the Access Port for its MAC address. Leo enters a new name for the Access Port, Eng-AP1, and its location, Eng. Offices.

WS2000 Use Cases 12-51

He sets the channel at 1, and notes the number. Access Ports channels should be separated as much as practical to minimize interference between them. The other engineering Access Port will use channel 4 and the marketing Access Port will use channel 7. He then sets the Power Level at the maximum setting of 100mW. Before he can change the channels, Leo checks the Channel Selection Mode. The default Channel Selection mode is set under the respective radio’s default screen. The default channel selection mode for ‘b’ radio is User Selection. Leo clicks the Channel Selection Mode button do display the Channel Selection Mode dialog.

In the dialog, he selects User Selection option and clicks the Ok button to close and return back to the AP screen. He also sees no reason to change the settings for Antenna Diversity, Support Short Preamble, RTS Threshold, or Beacon Settings. These parameters control some of the broadcast mechanics of an 802.11 conversation between mobile units and Access Ports. In most cases, there is no reason to change them.

12-52 WS2000 Wireless Switch System Reference Guide

He clicks the Apply button to save his changes. Leo then selects AP2, the second engineering Access Port. He gives it a new name, a location, and assigns it channel 4.

Leo clicks the Apply button to save the configuration for this Access Port. Leo then selects the third Access Port in the left menu. This will be the sales and marketing Access Port. Leo configures it similarly, but uses channel 7.

WS2000 Use Cases 12-53

Leo clicks Apply to save his changes. To avoid interference with the sales and marketing AP, Leo chooses channel 10 for the administration Access Port. He then enters the Access Port Name and Location.

Leo clicks the Apply button to save the changes for the administration Access Port.

12-54 WS2000 Wireless Switch System Reference Guide

The Access Ports are now configured. The next step is to specify access levels between the subnets.

12.26 Configuring Subnet Access Leo selects the Firewall --> Subnet Access item in the left menu. This screen determines what subnetto-subnet traffic is allowed.

The subnet access defaults every subnet having access to every other subnet and full access to the WAN. Leo wants to restrict subnet access so that marketing has no access to the engineering subnet and no access to the administration subnet. He would also like to restrict all of the subnets to HTTP, SMTP, and POP access to the WAN. First Leo will restrict access from the marketing subnet to the other subnets. He selects the cell in the matrix defined by From SalesSN on the left and by To Eng-SN above. Then, in the Rules section, he pulls down the menu to the left of all protocols and selects Deny. This will block all traffic originating in the marketing subnet and going to the engineering subnet except the named protocols. No protocols were selected, so no traffic will be allowed. Leo clicks on the Apply button to record this subnet access configuration.

WS2000 Use Cases 12-55

Similarly, Leo restricts access from the marketing subnet to the administration subnet.

Leo would also like to restrict traffic from all subnets to the WAN to just HTTP, SMTP, and POP protocols. He selects the cell in the matrix defined by From Eng-SN on the left and To WAN above. Then he uses the Rules pull down menu to select Deny and specifies that HTTP, SMTP and POP are the exceptions.

12-56 WS2000 Wireless Switch System Reference Guide

Similarly, he restricts the marketing and administration subnets in their access to the WAN.

Leo clicks the Apply button to record his changes. The subnet access is configured. Now Leo needs to set up VPN access to the Engineering Annex and test the installation.

WS2000 Use Cases 12-57

12.27 Configuring the VPN To configure a VPN link between WS2000s, the following must be specified: • The subnets on each end of the VPN link (tunnel) • The authentication method for allowing a connection • The encryption method for the content passed across the link Both WS2000s must be set up with complimentary information on each other.

Leo toggles open the WAN item in the left menu and selects VPN. Each VPN link between one subnet and another is called a tunnel.

12-58 WS2000 Wireless Switch System Reference Guide

Leo clicks the Add button to add a VPN tunnel. Now Leo specifies the network parameters for the tunnel. The Tunnel Name is simply a name by which to distinguish one tunnel from another. Leo names the tunnel â&#x20AC;&#x153;Eng2EngAnnex.â&#x20AC;? The Local Subnet is the subnet that will be networked over the VPN, in this case, the Engineering subnet. The Local WAN IP is the IP address for the interface that this WS2000 will show to the WS2000 on the other side of the VPN. Leo enters an unused, internal IP address, 192.168.24.198.

WS2000 Use Cases 12-59

The Remote Subnet specifies the subnet, on the other WS2000, to which the engineering subnet will be connected. The Remote Gateway and the Remote Subnet Mask describe the network interface on the other WS2000 switch. After Leo fills in these parameters, he clicks Apply to record the changes. Now Leo needs to specify the authentication and encryption methods for the VPN link. He selects the simplest alternative, Manual Key Settings, since the link is so short and relatively unexposed.

12-60 WS2000 Wireless Switch System Reference Guide

The AH Authentication protocol is used between the two WS2000 switches to authorize initialization of the VPN tunnel. The AH authentication method must match on both switches and the inbound key on one WS2000 must match the outbound key on the other. Leo selects Secure Hash Algorithm 1 or SHA1 as the method and enters inbound and outbound 40 character authentication keys. The inbound Security Parameter Index (SPI) for this WS2000 must match the outbound SPI from the other switch and vice versa. Leo enters 100 for the Inbound SPI and 101 for the Outbound SPI. The Encapsulating Security Payload or ESP is specified in the lower section. This specifies how the network packets will be encrypted between the two ends of the VPN tunnel. Leo chooses DES encryption and specifies the Inbound ESP Encryption Key so that it will match the Outbound ESP Encryption Key on the other WS2000. He also specifies the Outbound ESP Encryption Key on this WS2000 so that it will match the Inbound ESP Encryption Key on the other switch. Finally, the Inbound and Outbound SPI fields in the encryption section on this WS2000 must match the Outbound and Inbound SPIs on the other WS2000. Leo enters 110 for the Inbound SPI and 111 for the Outbound SPI. Leo clicks Ok to record the Manual Key Settings. Then he clicks the Apply button to confirm this configuration. The switch is now configured!

12.28 Installing the Access Ports and Testing The switch is now configured. Leo connects the switchâ&#x20AC;&#x2122;s WAN port to the VPN appliance that goes to the outside world. He gets three laptops and sets each of them to use DHCP for IP address assignment, 802.1x EAP for user authentication, and WPA-TKIP for data encryption over the wireless link. He uses the first laptop to connect to the engineering WLAN, the second to connect to the sales and marketing WLAN, and the third

WS2000 Use Cases 12-61

laptop to connect to the administration WLAN. He makes sure that laptops on each WLAN can connect to the WAN and to each other. After he has tested the three subnets, he installs the Access Ports in their permanent locations. He test coverage with the laptops, making sure each Access Port is covering its assigned area. He also unplugs each of the engineering Access Ports, in turn, to be sure that both are working properly. When everything seems to be working, he sends an email to the users telling them that the new wireless network is up and running!
